In their article on X-Men: First Class, Empire feature the pic of the main cast with some character tid bits.
On Caleb landry Jones as Banshee/Sean Cassidy..
An Irishman with a sonic scream in the comics, Jones' Cassidy is a young American here, the big lungs remain intact"
Jennifer Lawrence as Mystique..
Magneto's future accomplice starts off as Charles' BFF, shapeshifting into human form. "This is before her Rebecca Romijn mutant and proud days" laughs Lawrence
Rose Byrne as Dr Moira MacTaggert..
The only human in the group, Moira is the team's link with the CIA. "I love the idea of it being in the 60s" says Byrne. "It gives it a twinkle in the eye"
Nicholas Hoult as Beast/Hank McCoy..
The team's resident boffin, before his mutation later in the film as the big, blue bouncing Beast."He's very urbane and witty" says Hoult
James McAvoy as Charles Xavier..
"He's not a monk" says McAvoy, "He enjoys a drink, he's a sex pest! But you start to see his ego break down"
Cue rants and raves about "how dare they make Xavier a rapist" and so forth. Seriously though, I am a bit miffed that they changed Banshee's Irish origins, he was pretty much the only super hero we had:(. Anyway, they also had some stuff on Magneto and Havok but it's nothing we hadn't heard already.
X-Mem: First Class opens June 3rd.
