I'd swear that was Joe Pesci in the Misfits...
There's a scene wherea Pesci look- and sound-alike is sitting at the wheel of a parked car. He would have been 18 yrs.old, so it COULD be him. But he looks like he's 35 in this movie.
The credits are very limited, and the movie doesn't show up in his filmography. But I swear its him...
