The Solution Entertainment Group is handling international rights and will present the project to buyers at the Toronto International Film Festival.
Producers are Dawn Krantz, Stephen McEveety and Jon Burton. Dito Montiel (“A Guide to Recognizing Your Saints”) will direct from a screenplay by Adam Simon (“Synapse”).
Lisa Wilson and Myles Nestel from The Solution are exec producing “Man Down” alongside Roger Goff, Russell Geyser and Clay Pecorin.
The film follows a haunted Afghanistan war veteran who attempts to come to terms with his past while searching for his family in a post-apocalyptic America.
“When I read the script for the first time I knew it was something very special,” said Krantz, who produced “Doonby.”
Montiel and LaBeouf collaborated on 2006′s “A Guide to Recognizing Your Saints,” centered on Montiel’s youth in Astoria, N.Y. The film starred Robert Downey, Jr. as the present-day Montiel with LaBeouf as the younger version.
McEveety produced “The Passion of the Christ” and Burton exec produced “The Lego Movie.”
LaBeouf will be seen next opposite Brad Pitt in “Fury.” Oldman was seen most recently in “Dawn of Planet of the Apes” and Mara costarred in Netflix’s “House of Cards.”
The Solution has a trio of titles screening at Toronto — the world premiere of “The Forger,” starring John Travolta, Christopher Plummer and Tye Sheridan; Lynn Shelton’s “Laggies,” starring Keira Knightley, Chloe Grace Moretz and Sam Rockwell; and “Infinitely Polar Bear,” starring Mark Ruffalo and Zoe Saldana.
