"I'm not that complicated as an actor. I have a formula in which I work, yeah. But not like Sean Penn does. Sean is one of the few actors I know who can work like that, actually becoming the character he is playing, and get consistent results. I don't believe you can ever be someone else. You manifest different levels of your own personality to come up with a character"

Kiefer Sutherland is recommending that he has a formula for his acting, however it is not as complex as Sean Penn's. He admires Sean Penn's ability to become the character he is playing and get constant outcomes. He thinks that it is difficult to be somebody else, but rather, actors manifest various levels of their own character to create a character. This suggests that Sutherland believes that acting is more about understanding and expressing one's own emotions and experiences, rather than entirely transforming into another person. He thinks that by understanding and expressing one's own feelings, a star can create a believable character.
