Two adult brothers return to their well-preserved childhood bedroom in Pat Hazell and Matt Goldman’s Bunk Bed Brothers at the Marcus Center for the Performing Arts. The dialogue has the light comic pop one might expect from two playwrights who have written for television, but what really makes the show worth seeing is Hazell’s direction. Hazell places a great deal of trust in the comic instincts of lead actors John McGivern and Christopher Tarjan. The actors’ inventive work manages to keep things entertaining, even when the material they’re working with comes perilously close to being unfunny.

Bunk Bed Brothers continues through Nov. 15 at the Marcus Center.
