Robert De Niro seems resigned to the fact that he'll always be associated with the line, "You talking to me?"

"It's crazy, but what can you do?," says De Niro, who first uttered the line as crazed Travis Bickle in 1976's Taxi Driver. "It must have struck something with people. I think a lot of people probably do that. It's something that anybody can relate to."

De Niro himself actually gets a chance to poke a little fun at the famous line in his latest pic, The Adventures of Rocky & Bullwinkle. He utters the line as Fearless Leader and winds up getting one of the biggest laughs in the movie.

"When [director] Des McAnuff asked me if I wanted to do that, I said, 'All right, let me try, what the hell,' " he tells TV Guide Online. "So I started studying the scene to see how I had actually said it. I did it verbatim, you know."

While De Niro's best known for his dramatic roles, the actor says it was "fun" getting to play in a movie based on a cartoon. "There's not the pressure of worrying about whether you're believable or not. There's a certain type of believability, but not the type that I'm used to using or working for."

But not everybody's happy about DeNiro's latest role. "One of my kids, my 4-and-a-half-year-old son, didn't like that I was playing the bad guy," he says. Catch De Niro this fall in another comedy, Meet the Parents, co-starring Ben Stiller and Blythe Danner.
