They did the rounds earlier this week, but the first two posters for X-Men: First Class have now officially popped up in my inbox, and they reveal some interesting new details about the past lives of Professor X and Magneto. Not that they were called Charles and Erik - those names stayed the same no matter how shiny Magneto's helmet got. In fact, they used their first names throughout the rest of the X-Men films.

But there are other facts that we don't know about these mutants, and Matthew Vaughn's prequel may finally give us their full backstory...

Before he was Professor X... ... He could walk on water.	Before he was Magneto... ... He used to wet the bed.

For more prequel awesomeness (without the Jesus stunts or bed wetting), check out the X-Men: First Class trailer. Charles and Erik will be showing off their failed plumbing skills in cinemas on Friday 2nd June.
