After years of bit parts in TV and films, the Bridgton-based actor has a key role in director George Clooney’s upcoming film ‘The Tender Bar,’ which stars Ben Affleck.

Until this year, Matthew Delamater was taking his acting career one day at a time.

One day, after all, was the amount of time he spent on most TV and film sets. He’s worked steadily for about a decade, but often in small roles. He was credited as “bearded prison guard” in a 2018 episode of the Stephen King-inspired Hulu series “Castle Rock” and “gun salesman” in the 2017 comedy film “Daddy’s Home 2.”

Then, in February, he began two solid months on the set of the much-anticipated drama “The Tender Bar,” working side-by-side with Oscar winners George Clooney, the film’s director, and Ben Affleck, its star. The film is about a boy essentially raised by his bartender uncle (Affleck) and the bar’s patrons. Delamater plays one of those regulars, Joey D.
