Flight Risk supposedly started filming on June 16th, but was halted due to the SAG Strike. Recently, however, Gibson's Flight Risk was granted a waiver to resume filming.
Mel Gibson has only directed five feature films since his 1993 debut The Man Without a Face. He often takes long breaks between films; Hacksaw Ridge was released seven years ago. Before Gibson gets to Flight Risk, he is already in pre-production on The Passion of the Christ: Resurrection, a sequel to his 2004 box office hit.
