Hefner died last week at the age of 91, but Ratner has reportedly been set on directing the project since 2007.

Ratner acquired the rights to the film in 2015, after its previous rightsholder, Jerry Weintraub of Warner Bros., passed away.

Leto, who stars in the upcoming "Blade Runner 2049," will take on a role that THR writes was once meant for Robert Downey Jr.
