It’s rare to watch a film as rich as Lovell Holder and Roger Q. Mason’s “Lavender Men.” It’s based on a play. It looks like a play. It is intricate and complicated cinema. There are those who behave as though cinema and theater are polar opposites, and that to be “cinematic” is to evade any whiff of the “theatrical.” Remove thyself from a single location, and only then art thou in a film.

But film captures life and life takes place at the theater, at least whenever we’re in there. For those to whom all the stage is a world, those people who make live theater breathe , a film about their lives must take place on stage. And in “Lavender Men,” Roger Q. Mason plays a theater manager whose contributions to a rather unremarkable play about Abraham Lincoln are unsung, or only sung with the wrong pronouns.
