During our recent sit-downs with the cast of "X-Men: First Class" -- a prequel and the fourth film in the "X-Men" franchise -- the talk focused not so much on how the latest installment differs from the first three, but rather what separates "First Class" from all the other superhero-style movies opening this summer.

[article id="1664867"]James McAvoy and Michael Fassbender[/article] pointed to the film's universal theme of struggling to fit in, for instance. For their co-star Lucas Till, what makes "First Class" stand out is how fans connect to the unique characters, whereas the competition often relies more on fun to pull in moviegoers.

"I feel like the question I wished you would have asked me is, 'How awesome does this summer look?' Because you've got completely different things," Till said when we asked what separates his flick from the rest of the pack. "With 'Captain America,' you've got a 1940s pulp-movie feel, and I feel like that's going to be its own separate thing; fun and entertaining. And then you've got 'Thor,' which is, like, a cool 'He-Man' episode, which I was thoroughly surprised with. Then you've got 'Green Lantern,' which I thought was going to be stupid, but kind of looks like a cool cartoon.

"This one," Till continued, returning to "First Class," "There's so many metaphors to real life and there's actual character development. I feel like you care about the characters, then there's an ensemble cast, which they're trying to do with 'Justice League' and 'Avengers.'

Till suddenly spouting so many comic-book films both surprised and impressed his "First Class" co-star Rose Byrne. "You're like a lexicon for superhero movies," she said with awe. "You really are, you have an intelligent perspective and context for them; I don't."

At which point their co-star Zoë Kravitz joked that Byrne now had the hots for Till.

"What are you doing later?" Byrne joked to Till.
