Even Alec Baldwin gets starstruck sometimes.

On Letterman Wednesday night Baldwin described what happened when he was filming "The Good Shepherd" with director Robert De Niro. Every time De Niro yelled cut the first few days to give notes, Baldwin was lost in his head having "Raging Bull" fantasies.

He then told the story of being in an elevator with Burt Lancaster. Baldwin did an impression of the screen legend standing in profile, knowing he was being stared at, and letting Baldwin soak him in.

Baldwin is currently doing promotion for "It's Complicated." WATCH:
