He just has to keep the faith

"I didn't model it specifically on another creature. Everything matters, especially in a period piece. We're talking about physicality and articulation of language. Especially when Daniel is there," he said of Day-Lewis, famous for his immersion in roles. "He's that guy. He just is."

Dano does his share of research for parts, though he acknowledges that in preparation for "Fast Food Nation" he applied at a few McDonald's restaurants but never landed the job. He suspects that at least one franchise staff knew he was an actor.

Apart from the improbable success of "Sunshine," Dano's resume is remarkably clear of blockbusters, but he doesn't consciously seek independent film work.

"I don't feel pressure to do this type of film or that type; hopefully that's not too naive a thing to say," he said.

"The more passionate you become about what you do, the more it means to you -- it's important to enter into a project with that, something ineffable, intangible."
