Lars von Trier’s The House That Jack Built, which is currently in production, could be his last film according to Deadline.

Lars von Trier told reporters at a press event last week that “I feel like sh*t, I have so much anxiety. I think I’m getting too old for this. Just to work on the set and rush around with some actors, even though they are very sweet, it is a challenge of dimensions. I don’t think I can make any more films after this one.”

The House That Jack Built takes place over twelve years and follows the development of a serial killer through his five most important murders. Matt Dillon stars as Jack, and Uma Thurman, Siobhan Fallon Hogan, Sofie Gråbøl and Riley Keough are set to play his victims.

During the same press conference, von Trier made no attempt to hide the fact that his new movie is going to be especially graphic, even by his standards. “There were so many people we sent the script to, who said they would do anything to work with me, except this script,” he said.

The House That Jack Built is currently filming in Sweden and Denmark, with the film aiming to premiere at the Cannes Film Festival in 2018.
