‘Snowpiercer’ Showrunner Josh Friedman Exits TNT

Friedman wrote the pilot and also served as executive producer

Josh Friedman, showrunner of TNT’s upcoming series “Snowpiercer,” is leaving the network, a network spokesperson told TheWrap.

Friedman wrote the pilot of the series, which was picked up by TNT just this month, and was also an executive producer on the show. A person close to the network told Variety that “creative differences” caused the split.

The series is based on Bong Joon Ho’s 2013 film of the same name, about a ginormous train that circles the frozen wasteland the earth has become and houses what is left of the human race. While the train moves, its inhabitants struggle with the same political and culture issues the world has dealt with for centuries, including social injustice, class warfare and the fight for survival.

Jennifer Connelly, Daveed Diggs, Mickey Sumner, Susan Park, Benjamin Haigh, Sasha Frolova, Katie McGuinness, Alison Wright, Annalise Basso, Sam Otto, Roberto Urbina, Sheila Vand and Lena Hall make up the cast.

The reboot is a co-production between Tomorrow Studios and Turner’s Studio T, as well as CJ Entertainment. Scott Derrickson directed the pilot, which was written by Josh Friedman.

Tomorrow Studios’ Marty Adelstein and Becky Clements executive producer, along with the original film’s Bong Joon Ho, Park Chan-wook, Lee Tae-hun and Dooho Choi.
