Kenneth Branagh thinks it's very important for him to have variety in his acting roles.

The actor has taken on many different characters throughout his career and says it's a good thing because he doesn't get typecast and can show off his talents in lots of ways.

Speaking about his decision to play a villain in the 'Jack Ryan' film: ''Variety is very, very good. Going from medium to medium, if you get the chance to do it, from theatre to television to film, which are all distinctly different, keeps me sharp. What works in one doesn't work in the other, and you have to be looking for the truth of the performance, whatever way that medium might demand. Jack Ryan is a very fast-paced, very contemporary, very action-driven thriller. I don't tend to think of him as a villain, but if you're playing a villain, you don't think of him as a villain. You just think, 'My guy.' The character is a great anti-thesis, but it isn't as simple as that. It's great to see a character in this film with Jack Ryan. It's just a very strong, very interesting, complicated, complex character.''

As well as starring in the future movie, Kenneth will also direct the project and says it's something he's looking forward to.

He told ''When the project first came my way, it was really to do that. I had a long time to think about that prospect, before actually eventually having them ask me to direct it. And then, we put aside the issue of me being in it for awhile 'cause there were so many other things to deal with. Literally, months later, Paramount said, 'Well, do you think you might?', and I said, 'Yeah, I think I'd like to.' ''
