Although the movie is slated to start filming this summer, director Damián Szifron has exited Warner Bros.' Six Billion Dollar Man.

According to The Hollywood Reporter, "creative differences" are to be blamed for Szifron's split with the studio. However, it's unknown what specifically caused Szifron, who also co-wrote the script, to part with the project.

Szifron took over the project after the departure of Lone Survivor director Peter Berg in 2015.
