Dezi Gallegos, front center, is the write, director and star of the new comedy play "Quite Dead." The cast also features, from left, Kennedy Petersen, Amanda Pedersen, Gabe Stephens (kissing Amanda), Lukas Thompson and Natalie Herman.

While some high school students might aspire to become Buster Posey of the San Francisco Giants, Dezi Gallegos of Petaluma would rather be John Cleese of Monty Python’s Flying Circus.

Gallegos, a 17-year-old senior at Marin Academy, is the author, director and star of a new two-act comedy play, titled “Quite Dead,” with a very British flavor.

“In my junior year, on my drive to school, I had this idea for a British comedy, inspired by the humor of Monty Python and the movie, ‘Death at a Funeral,’” Gallegos said.

With seven other veterans of the Cinnabar Young Repertory Theater training program in Petaluma, ranging in age from 16 to 20, Gallegos will perform the play at 7:30 p.m. two Sundays next month, Nov. 4 and 11, at the Cinnabar Theater.

“I’ve been doing plays at Cinnabar Theater since I was 8 years old. I have been in about 20 shows there,” Gallegos said.

Gallegos plays Charles Logan, a young Brit who comes home for a family reunion and soon finds himself deluged in domestic chaos.

“Charles is sort of the straight man,” Gallegos said.

Gallegos’ cast is as seasoned as he is. All together, they’ve been in a total of 57 shows at the Cinnabar.

“This play is not some rinky-dink kid production,” he said. “It’s very professional.”
