The full Prometheus trailer has parked its shiny bum on the internet - and as far as teasers go, it's pretty damn teasing.

We still don't know that much about Ridley Scott's prequel-but-not-a-prequel-but-still-connected-to-the-Alien-franchise-but-not-really mystery film. The official synopsis reads something like: "A team of explorers find a clue to the origins of man on Earth, leading them on a journey to the darkest corners of the universe... There, they must fight a terrifying battle to save the future of the human race."

We seem to be looking at what happened in the lead up to the events on LV-426 in the first Alien film. But Ridley's been pretty adamant that this isn't a directly linking prequel.

Yet everything about this screams Alien. The pods littering the ground around Michael Fassbender's character. The familiar outline of the infamous space jockey's ship. The way the titles appear in the same gradual procession of vertical and horizontal bars. 

So what's it all about? Like all the best teasers, Prometheus' trailer doesn't answer any of our questions - it just asks a load more. When Ridley Scott does answer them in 2012, it should be something very special. As long as you forget that this is the director who also made Robin Hood and A Good Year.

Read on for the full Prometheus trailer. Then get very excited.

When it comes to amusing interviews, you can't beat a bit of Simon Pegg and Nick Frost. If you put them together in a press conference with Kristen Wiig, Sigourney Weaver, Joe Lo Tuglio, Jason Bateman and director Greg Mottola, you've got the greatest roomful of funny people since the film Paul. Which, by an coincidence, is exactly what they were there to talk about.

Comprising of Arrested Development actors, sci-fi geeks, Adventureland directors and movie legends, the ensemble spent a lot of time throwing around entertaining in-jokes. Here's what they had to say about aliens, Christians, and Steven Spielberg...

After long months of waiting, Peggy and Frosty fans can be happy to see the teaser trailer for Paul. And when they say teaser, they mean teaser - it doesn't show you much.

A sci-fi comedy about an alien (called Paul) who gatecrashes a road trip across America by two British geeks. That's about all you're getting from this video, apart from a few lines from Seth Rogen's foul-mouthed E.T.

The rest is just namedrops, although they are pretty impressive names: Greg Mottola (of Adventureland fame) at the helm, Jason Bateman and Sigourney Weaver in the supporting cast, and a bit of Kristen Wiig to boot.

This could be amazing. It's certainly a bit more promising than Burke & Hare. But it's also a complete cypher. Paul will be unveiled properly next February. Read on for the video.

MIB III just got a lot more interesting: Sharlto Copley is in talks to star in the sci-fi sequel, along with Alec Baldwin and Gemma Arterton.

Barry Sonnenfeld's 3D entry in the series is probably one of the most pointless ideas since someone invented the chickpea, but the wave of new talent certainly makes it more intriguing.

The District 9 star is negotiating for the part of "a fast-talking Yoda-type alien" - a description which sounds horrible, but probably quite apt for the improv-heavy comedian. Alex Baldwin, meanwhile, will be the head of MIB in the 60s, with Gemma Arterton looking at the role of his secretary.

MIB III still stars Will Smith and Tommy Lee Jones as Agents Jay and Kay, who travel back in time to 1969 to stop evil villain Yaz (Jemaine Clement). And they totally meet a younger version of Tommy Lee Jones (Josh Brolin). Meanwhile, Emma Thompson appears as the modern day MIB chief. Just in case the other names weren't exciting enough for you.

I shouldn't be so easily won over by the prospect of added Sharlto Copley to anything. On the other hand, I clearly should. Discuss. 

Natalie Portman is looking the favourite in the hunt for the lead female role for Ridley Scott's Alien prequel. The person she'll have to beat? Noomi Rapace.

With Lost's key player Damon Lindelof having recently finished a new draft of the script, Scott is still casting about for his feisty female star. And Natalie Portman is pretty much available, now that she's dropped out of Pride and Prejudice and Zombies (which she's producing) and also dropped out of Alfonso Cuaron's Gravity.

Studio peeps seem pleased with Lindelof's work so far, with the leading role taking the form of a female military general. Scott's been meeting with a lot of actresses in the preparation for what is generally thought to be a return to the original Alien's suspenseful horror feel. The director's already met with Noomi and liked her a lot, but Natalie Portman is top of the list, and a pretty solid choice too. There's only one way to settle this... FIGHT!

Hot on the heels of Super 8's recent casting news, Ain't It Cool News have published a string of pictures from the secretive sci-fi. Not official photos, of course, seeing as this is a JJ Abrams' film - these are on set snaps from the location filming in West Virginia.

Converting Weirton into 1979 Lillian Heights, Ohio, the alien flick co-produced by Steven Spielberg is conceived as an homage to Spielberg's works like E.T. and Close Encounters. Judging by these pictures, they've certainly nailed the small-town aspect of it.

Starring Kyle Chandler and Elle Fanning (and now Noah Emmerich, Zach Mills Ryan Lee and Ron Eldard too), Super 8 sees some kids accidentally shoot an alien (escaped from a secure train heading out of Area 51) on their Super 8 home videos.

You can check out the trailer over here, or read on for more set photos. 

Anyone thinking that Peter Berg's adaptation of Battleship is lacking a little authority can consider themselves proper told like, because Berg is adding another piece to his Hasbro board game: Liam Neeson. Yes, Aslan has boarded the boat movie.

Colonel Hannibal Smith will be switching uniform to play Admiral Shane, a respected, sexy, Liam Neeson lookalike, who happens to be involved with the plot. He has a model daughter (Brooklyn Decker) to go with his model ships, and is facing the prospect of Taylor Kitsch's hero dating her.

Neeson joins the cast, which has already set sail to Hawaii to start shooting. Rounding up the ranks are Alexander Skarsgaard (the hero's older brother) and Rihanna, playing a weapons expert - yes, you didn't imagine that one. It's still true.

Battleship will see a fleet of humans fending off attack from water-loving aliens, who want something from Earth's oceans. Probably the water. No doubt Kitsch's cocky commander will save the day, battle some ships and bag Liam Neeson's daughter. Although we all know what happened last time someone did that...

Expect this baby to land in May next year, when the world will finally get to hear the immortal tagline: Battleship: Ships Will Battle. Or something.

Ridley Scott has approached Gemma Arterton about appearing in his prequel to Alien. After standing out for all the wrong reasons in Prince of Persia and Clash of the Titans, the British actress impressed the director with her turn in The Disappearance of Alice Creed.

After seeing her raw performance in the indie thriller, Scott is arranging to meet Arterton to discuss the 3D sci-fi horrors. As she put it: "He wants me to meet for Aliens: The Remake or something."

Ridley is not the only person won over by Arterton's acting: she's also just been cast in Christopher Nolan's upcoming adaptation of The Keys to the Street. Based on the Ruth Rendell novel and scripted by Nolan himself (although since subject to some dubious rewrites), the screenplay has been sitting around since his debut, Following. The Inception director, however, will no longer be at the helm.

Arterton will play Mary, a bone marrow donor who enters into a relationship with the man whose life she has saved. Talking again to The Times, she voiced her surprise that the film had been sitting around for so many years.

Gemma Arterton will next be seen in Stephen Frears' Tamara Drewe (out this week) - a step up in quality from Quantum of Solace. You've got to admit, her slate is shaping up pretty nicely for the near future. Except for Clash of the Titans 2, of couse. 

What with Battle: Los Angeles and Skyline, you might have had enough of alien invasions and other such extra-terrestrial threats. But on the opposite scale of things comes an intriguing new viral site launched for a completely unknown film: They're Here.

With pretty much nothing else on the site apart from a giant red clock counting down and some ominous phrases, there's not much to go on. Just a promise to reveal all on 10-10-10. Whatever there is to reveal. Until then, there's some Twitter action going on from a (presumably fictional) user called Paul Geist. And a very short bit of teaser video on YouTube. Which was shot near Falkirk, Scotland.

That location plus the UK URL of the site suggests a low budget feature, which promises to have a trailer arriving later this month before the big reveal. Will this end up linked to a bigger Hollywood project? Given the activity (both promotional and legal) going on with invasion flicks Battle: Los Angeles and Skyline, it seems unlikely. We'll be keeping a tab on this potentially interesting and most likely indie bit of sci-fi.

The website is over here, and you can read on for their video of a UFO sighting.

Bob Hoskins, the man who has taken down rival gangsters, dressed up as Super Mario, and worked with animated rabbits, has found himself a new hobby: fighting aliens.

Hoskins has signed on to the British sci-fi flick Transmission, alongside Jason Flemyng, Willem Dafoe and Talulah Riley. It's a neat cast list to see off an alien invasion, which is fortunately exactly what happens. Although we don't know much else about the plot.

Bob's long Friday goes bad when extra-terrestrial folks attack Earth during a solar eclipse, bringing with them 3D cameras. Described by Moviehole as "Pitch Black meets 28 Days Later", Transmission has an Oscar-winner at its helm: Roger Christian, the man not only involved in the art direction on Stars and Alien, but also the director of Battlefield Earth. I'll let you figure out which one the Oscar was for.
