The first "X-Men" film was released in 2000 and pitted an aged Magneto and Charles Xavier against each other. "X-Men: First Class" (2011) tells how they became friends before becoming enemies. Both films start with the same scene, of Magneto as a boy in a Nazi concentration camp.

The second film's scene was a nearly shot-for-shot remake of the first. I say nearly because, in "First Class," this scene introduces a new character, Sebastian Shaw (played by Kevin Bacon).

"First Class" director and writer Matthew Vaughn said the camp scene was the first one he wrote in the script. "I thought, 'What's the best way of doing a prequel?'" he told DenofGeek.com. "I thought, 'Let's just start it shot for shot with the beginning of 'X-Men,' and then let's see what happened after."

The new film had to use new actors, of course -- the boy who played Magneto in 2000, Brett Morris, was a man by 2011 (he now works as a writer and producer in his native Toronto).
