It's no secret that the 2000 blockbuster X-Men helped pave the way for the wealth of comic book movies seen every year. Unlike in the comic books, however, we haven't seen any superheroes cross over into different franchises, although it almost happened in 2002's Spider-Man.

Hugh Jackman reveals that he was almost set to appear as Wolverine in director Sam Raimi's blockbuster, although it wasn't a studio or rights issue that prevented this from happening. Take a look at what the actor had to say, while promoting his upcoming thriller Prisoners.

"In the first Spider-Man -- Kevin Feige reminded me of this -- we really tried to get me to come on and do something, whether it was a gag or just to walk through the shot or something. The problem was, we couldn't find the suit. The suit was stuck in some thing. And so when they were in New York when I was there, we couldn't get it together.

So, you know, I actually asked some high level people about it. Because the optimist in me goes, 'Why not? Why can't we do it? You know, a split cast or whatever?' And someone reminded that the amount of money Fox paid compared to the amount of money Disney paid is very different [laughs]. So how you split that pie up? God knows. But in the comic books, what's great about it is they're just mashing together all the time -- and it's awesome. And people are like, 'Yeah, well, let's get this one with that!' And, you know, I still think, one day, there may be an ability to do it."
