Stephen Collins is in talks for Fox’s “The Three Stooges” as Mr. Harter, who attempts to adopt the stooges from an orphanage for a nefarious purpose.

Helmed by the Farrelly Brothers, Collins joins recent additions Larry David as Sister Mary-Mengele and Jane Lynch as Mother Superior.

Sean Hayes and Will Sasso are set to star as Larry Fine and Curly Howard, respectively, and TV thesp Chris Diamantopoulos is the frontrunner to play Moe Howard.

The Farrellys are producing with their Conundrum partner Bradley Thomas and Charles B. Wessler, while Earl Benjamin, the gatekeeper of the Stooges’ estate, will exec produce. “Stooges” was originally developed at MGM before it landed at Fox, where current plan calls for the Farrellys to deliver a PG-rated pic divided into three, 27-minute segments driven by physical comedy.

Collins most recently appeared in the ABC series “No Ordinary Family.” In addition, “Super Sunday,” a play he wrote, is now playing at the Moth Theatre in Los Angeles.

Collins is repped by Envision Entertainment and APA.
