Nicholas Hoult was chosen for the role of Beast in 'X-Men: First Class' because he has "charm and innocence".
The 'Single Man' star picked up leading roles in both the 'X-Men' prequel - alongside James McAvoy and January Jones - and forthcoming movie 'Jack the Giant Killer', and Bryan Singer, who is involved in the production of both, said he was perfect for the parts.
He said: "He's a really fine actor, and he also has a charm and an innocence that I noticed when we cast him as Beast.
"He needed those qualities because in 'X-Men' he's this excitable scientist who's going through a transformation, and in Jack he's a lovestruck farmboy who also transforms in the movie.
"He falls for a princess and then goes off to rescue her. It's a very traditional fairytale."
The project is one of a number for the up-and-coming British actor - he is also signed on to star in 'Warm Bodies' about a relationship between a zombie and the girlfriend of one of his victims.
