Henry Winkler and son Max Winkler are teaming for HBO limited series King Rex

Deadline

The Barry star is set to expand his relationship with HBO while teaming up with his writer-director son for the first time in King Rex, a limited series in development at HBO based on the 1980 Texas Monthly article “Rex Cauble and the Cowboy Mafia" by Lawrence Wright. According to Deadline, King Rex, written by Trey Selman, "will tell the story explores a buried treasure of a True Crime mystery—how a North Texas kingdom got itself smashed to pieces by a judge’s gavel, the IRS and the FBI. Henry Winkler will play the gangster Cauble and insiders say the character is straight out of the gangster pic Casino and unlike any character the Emmy-winner has ever played." Max Winkler is expected to direct the pilot, with Malcolm Spellman and Nichelle Tramble Spellman serving as executive producers.
