If you have a so-so screenplay, it doesn’t hurt to have talented people around to make the most of it. Take, for instance, “The Instigators,” a buddy crime comedy that, after a limited theatrical rollout last week, lands this week on Apple TV+. The movie is better than it has any right to be thanks largely to the chemistry of stars — and ol’ Boston pals — Matt Damon and Casey Affleck.

It’s better for the supporting work of talented Hong Chau and, to a lesser degree, by big-name bit players including Michael Stuhlbarg, Ving Rhames, Alfred Molina and Paul Walter Hauser. Last but not least, “The Instigators” benefits — greatly — from having a well-above-average director in Doug Liman, who long ago directed Damon in “The Bourne Identity” and keeps this romp engaging and moving along to, well, let’s say an acceptable ending. Set in Beantown, “The Instigators” first introduces us to Damon’s Rory, a former Marine who hasn’t seen much go right in his life, in a session with psychiatrist Dr.

Donna Rivera (Chau). He won’t reveal much to his caring doctor but does mention that he’d had the thought of ending his life in a year if things didn’t turn around for him. “And when did you come up with this plan?” she asks.

“It was about a year ago.” Desperate to generate a little more than $32,000 to address a situation with his son, Rory meets with gangster Mr. Besegai (Stuhlbarg), who wants to rip off Boston Mayor Miccelli (Rob Perlman) on wha.
