HOLLYWOOD — The rule at the door is the whole idea: nobody is told what will be read, and nobody is told who is reading it, until the actors take their chairs and the first page turns.

For the ninth year, a small theater off Santa Monica Boulevard sold out its annual benefit table read this week, a night that raises money for a neighborhood food bank by doing the opposite of almost every other charity event in town. There is no red carpet. No names are announced in advance. The performers are working actors — the kind who book two lines on a network drama and voice a video game and teach a scene class to cover the gap — reading a screenplay chosen in secret by the organizers, sometimes a famous one, sometimes a script that never got made.

“The second you announce a star, the night becomes about the star, and the ticket price triples, and the food bank becomes the excuse instead of the point,” said Dahlia Reyes-Okon, 46, a casting associate who founded the reading after a slow year left her with time and a mailing list. “I wanted a room where the reason you bought the ticket was the reason. The pantry. Not the selfie.”

The math is unglamorous and, this year, better than expected. The theater seats a little under two hundred, tickets ran forty dollars, and a silent auction of donated oddities — a day on a sound stage, a retired prop, a voice-actor’s afternoon recording a child’s birthday message — pushed the night’s take past what the organizers had projected. The food bank’s director, Warren Achebe, said the single evening covers a meaningful slice of the pantry’s summer, when school meal programs pause and demand climbs.

“Summer is our hard season. The kids who eat at school are home, and the families feel it,” Achebe said, working the lobby table where volunteers counted envelopes. “One night like this doesn’t fix that. It buys us weeks we didn’t have. I’ll take weeks.”

The performers work for free and seem to prize the anonymity as much as the audience does. A character actor named Ruben Castellano, 52, who has spent thirty years as a face people recognize without placing, read three roles Wednesday and said the format is a relief. “No one’s watching to see if I’m still famous, because I never was,” he said. “They’re watching a story. I get to just act, which is the part I actually like.”

This year’s script stayed secret until the lights came up — a comedy that never made it to production, its writer sitting anonymously in the third row, hearing the laughs the movie never got. Reyes-Okon said she has already begun the quiet work of choosing next year’s, a decision she guards the way other people guard a will. The theater has asked her to add a second night. She is thinking about it, she said, and refusing, as always, to say what she has in mind.
