Tickets to Jason Reitman’s Live Reads of films including “Shampoo” and “The Princess Bride” have become some of the hottest commodities in town: The Feb. 16 perf of the Film Independent at LACMA series is already sold out, though stand-by tix are available.

Performers including Steve Carell, Natalie Portman, Pierce Brosnan and Diane Lane have joined thesps from the helmer’s virtual stock company like Patton Oswalt and J.K. Simmons for the off-the-cuff and often uproarious events.

Reitman isn’t dropping any hints as to screenplays for the next two reads, but they’ll probably be beloved cult titles like the two chosen for previous perfs: “The Breakfast Club” and “The Apartment.”

The Live Reads, part of LACMA’s newly revitalized film series curated by Elvis Mitchell, are a lively way to get film lovers involved in a community experience that can’t be duplicated at home.

At Thursday’s performance, of the sexy 1975 dark comedy “Shampoo,” Reitman made the point that the show wouldn’t be taped.

The “Young Adult” helmer assembles an impressive group for each read, with the “Shampoo” cast including Bradley Cooper in the Warren Beatty role, Kate Hudson reprising her mother Goldie Hawn’s part and Lena Dunham as an uncanny new-generation Carrie Fisher.

To help set the film’s atmosphere on the bare stage, stills from the pic are projected above the actors, with the original actors digitally removed by Reitman’s fave title company Smith & Lee.

Tickets for the March reading will go on sale Feb. 19, and they usually sell out within a few hours.
