Written and directed by Onur Tukel, the movie is about "two bitter rivals whose grudge match spans a lifetime."
"Struggling outsider artist Ashley Miller [Heche] and wealthy housewife Veronica Salt [Oh] were close in college, but haven't seen each other since. When they find themselves attending the same glitzy birthday party, verbal barbs lead to fisticuffs and an all-out brawl that will keep these two locked in combat for years to come. Alicia Silverstone will play Ashley's love interest, Lisa."
"I expected the lead performances to be brilliant, but what they did blew my mind," Tukel said in a statement about Oh and Heche. "The fight scenes are also insanely intense. We've made a very funny comedy here, but it's also tragically dark. I'm so proud of what the cast and crew accomplished. It was so collaborative that I feel like I didn't do much work at all. I just sat back and watched a bunch of young, passionate people pull this movie together. It was magical."
"We worked with Onur on his previous... films, and his Catfight screenplay had us hooked from the very beginning. We look forward to seeing this latest collaboration come to fruition," added MPI Media Group's Greg Newman.
No anticipated release date has been announced yet.
Tukel's credits include Applesauce, Summer of Blood and Richard's Wedding.
Heche has starred in Hung, Psycho and Six Days Seven Nights, while Oh is famous for her work in Grey's Anatomy and Sideways. Silverstone is known for her performances in the movies Clueless and Excess Baggage.
