We all know Titans Will Clash. But now Potter Will Clash too. In 3-D. Thanks to Titan's positive testing, the final two instalments of Rowling's wizard franchise will be bumped into third dimension as well - something fast becoming standard practise for big summer blockbusters.

Warners Bros haven't officially confirmed this, but rumours have been rife (over at MarketSaw) of their tentpole releases being converted to cash cows (at a cost of $5 million apiece). Knocking Titan's release date back by two weeks is a direct casualty, but Potter has time to recover from the blow: he'll continue to uncover the Deathly Hallows in November this year and July of next. Now he just needs some snazzy glasses - Luna's already got some.

Well, it's official. There you go. Done and dusted. Avatar is the king of the world's box office. Fox confirmed that Titanic's title was lost to Cameron's successor early Monday following another massive haul over the weekend - it's now taken $1.292 billion in international receipts, $50 million ahead of Titanic.

With 70% of Avatar's income coming from oversees territories, Cameron still hasn't topped Titanic's domestic takings yet - he's on $551 million compared to $600 million in the US. Then again, technicalities can be trotted out all over the place; taking into account inflation, Titanic's worldwide record is actually closer to $2.5 billion. Let alone the skew 3-D prices put on Avatar's tickets. But is it wrong to take Cameron's title away from him? Perhaps. Unless he gets that Oscar too. In which case I'll be the first to roll out the old fact that Gone with the Wind's adjusted box office is still up at the $6 billion pound mark. No matter how big your blue people are, that's a hard target to beat.

Marc Webb has been confirmed as the director of the next Spider-Man trilogy. Following rumours of his surprise status as contender to Sam Raimi's crown, Marvel and Sony officially announced that the deal has now been spun and signed for.

The director of (500) Days of Summer, nominated for two Golden Globes and three Independent Spirit Awards, is excited by the opportunity given to him: "This is a dream come true and I couldn't be more aware of the challenge, responsibility, or opportunity. Sam Raimi's virtuoso rendering of Spider-Man is a humbling precedent to follow and build upon."

Webb added: "I think the Spider-Man mythology transcends not only generations but directors as well. I am signing on not to 'take over' from Sam. That would be impossible. Not to mention arrogant. I'm here because there's an opportunity for ideas, stories, and histories that will add a new dimension, canvas, and creative voice to Spider-Man.

After booting Sam Raimi out over massive disagreements (mostly to do with casting John Malkovich), Sony have been working away at a Spidey reboot for 2012. With James Vanderbilt's script in place, and a director who knows how to handle young adults and emotions - and costs less - the studio are sitting pretty smug on this one. And with the quick appointment of Sam's successor, their release date should remain unchanged: production begins later this year.

Amy Pascal, co-Chairman of Sony issued the following statement: "At its core, Spider-Man is a small, intimate human story about an everyday teenager that takes place in an epic super-human world. The key for us was to identify filmmakers who could give sharp focus to Peter Parker's life. We wanted someone who could capture the awe of being in Peter's shoes so the audience could experience his sense of discovery while giving real heart to the emotion, anxiety, and recklessness of that age... We believe Marc Webb is the perfect choice to bring us on that journey."

It's hard to disagree with that. I just hope he chooses someone decent to play Peter Parker. And by decent I mean not Robert Pattinson.

Director: Louis Leterrier
Cast: Sam Worthington, Ralph Fiennes, Liam Neeson
Certificate: TBC
Release Date: Friday 26th March

The ultimate struggle for power pits men against kings and kings against gods. But the war between the gods themselves could destroy the world. Born of a god but raised as a man, Perseus (Sam Worthington) is helpless to save his family from Hades (Ralph Fiennes), vengeful god of the underworl

With nothing left to lose, Perseus volunteers to lead a dangerous mission to defeat Hades before he can seize power from Zeus (Liam Neeson) and unleash hell on earth. Leading a daring band of warriors, Perseus sets off on a perilous journey deep into forbidden worlds. Battling unholy demons and fearsome beasts, he will only survive if he can accept his power as a god, defy his fate and create his own destiny.

Well, that didn't take very long. Only yesterday was it in third place having hopped the total gross of Pirates of the Caribbean 3. Now, after making those crucial few more millions, Avatar has taken second place in the box office from Return of the King. Sorry, Peter. Cameron means business now.

With $1.14 billion taken across the globe, James Cameron's 3-D blue-fest has topped the $1.1 billion Peter Jackson clocked up with the final part of his fantasy trilogy. But even Lord of the Rings couldn't prevent this from happening. And with competition from the likes of, erm, It's Complicated, and The Road, Avatar isn't going anyway but up.

It looks like a long way to $1.842 billion, but honestly? I think it's pretty much inevitable now. Even if James himself has to pay for his entire extended family to see it another 5 times each - let's face it, he could afford the 3-D ticket price.

$1.098 billion. That's what Avatar's earned so far. In just 19 days, James Cameron's 3-D epic has leapfrogged Pirates of the Caribbean: Dead Man's Chest into 3rd place for all-time box office takings. Disney's sequel got $1.066 billion over 150 odd days, so it's pretty good going for the shiny blue ewoks.

Next on the ladder is Return of the King, whose colossal $1.191 billion seems less towering against the power of the Na'vi. Then it's the inevitable climb towards Titanic's epic record of $.1842 billion. Even that is guaranteed to follow over the coming weeks. After all, it's only been 19 days. I'll just say that again: 19 days.

Avatar has grossed $367.5 million in the US, with $731.2m worldwide. And so big Cameron takes on ickle Cameron in a race to the top of the money tree. With 3-D pricing on the older Cameron's side, this could well get ugly...

For reshoots, that is. Yes, Louis Leterrier's Clash of the Titans, having wrapped shooting, is now set to start filming all over again next January. That wouldn't normally be a problem, but then it is being released in March.

Chatting to the LA Times at an Avatar event, star Sam Worthington revealed that they would be rebooting production after Warner Bros "cut loose with some money". More Clash for our Titans, then, it seems. Especially given that they're looking at an IMAX release and may even turn it into a 3-D affair (can you spell Kraken?)

It all sounds a bit pressured ("we'll be right up against it", Sam admits) but perhaps it's a necessary thing: after all, Worthington also concedes that there were some "creaky parts that we knew were creaky and that we knew were going to be creaky going into it." So once they're fixed, it will all be gung-ho crash-bang ker-ching, right?

Sam adds: "The studio is also letting us add some gods and scenes." Oh, well that's ok then. I'm completely reassured. Clash of the Titans: now with added Gods.

It's out today (and we frickin' loved it by the way), but in case you still need a Cameron fix before you catch Avatar yourself, here's some fresh new clips to whet your appetite. It's not in 3-D and i-Flicks is far from an IMAX screen, but there's something clearly wrong with you if you don't enjoy any of this at all. Still, Sigourney Weaver in full scientist mode may not be your cup of tea. In which case head over to our videos section for the trailer itself and a lovely eyeball-hugging trip round Pandora.

But if inter-planetary tourism ain't your style, read on for the full clips. One of them has blue people in it. Happy Avatar Day everyone.

Well, after that spate of posters from Facebookland, Disney have gone the whole hog and released the full trailer for Tim Burton's Alice in Wonderland. Yay. Now, with lots of lovely shots of flying hats, CGI rabbits and an oddly proportioned Helena Bonham-Carter, we can finally discern the actual plot for Burton's bizarre descent into Lewis Carroll's classic creation. Here goes:

Alice, now 19 years old, has just been proposed to by some red-headed freak. Running away from the horrible offer (did I mention he was a ginger?) she ends up back in Wonderland, where the Red Queen has taken over the whole world. And so, with the help of her old friends (who all recognise her instantly), she sets about restoring the balance to Wonderland, fighting on the side of Anna Hathaway's White Queen.

It's a nice twist on a well-known tale, one with broken windmills, freaky trees, smoky landscapes and eerie performances. In other words, it's exactly what we all expected: a Tim Burton film. Awesome.

Disney's 3-D adaptation hits cinemas next March. See the original teaser over here, or read on for the brand new video.
