The final scene - isn't that Joe Pesci?

In the final scene of this GREAT movie the character played by Tuesday Weld meets a new boyfriend. The actor very much looks like a young Joe Pesci, who would become famous about 15 years later (Goodfellas, My Cousin Vinny etc). He is not in the credits and Pretty Poison does not figure in Pesci's imdb filmography. This fact and also the small but very good and memorable part intrigued me very much. Anybody agrees, disagrees, knows something about this boyfriend actor??
