Mandalay Pictures will produce and Summit's production president Erik Feig and vice president of production Jean Song will oversee for the company. Summit holds worldwide rights.
The story centres on a harried orderly who has 10 hours to transport a seemingly stable mental patient across Los Angeles in order to get a slice of his charge's inheritance. Chaos ensues.
'Mental is a high concept, classic comedy with great opportunity for a new comic duo,' Feig said. 'It is exactly the type of film we at Summit are interested in making geared toward the global audience.'
'We were excited to read Bear Aderhold and Tom Sullivan's terrific comic two-hander and to find a second picture to make with our friends at Summit, as the company continues to build its impressive distribution slate,' Mandalay president Cathy Schulman said.
Mandalay executive vice president David Zelon, who is currently on set in Orlando filming Mandalay and Summit's teen fight club drama Get Some, brought the project to Feig.
Aderhold and Sullivan are represented by Trevor Astbury and Mark Ross at Paradigm, Brad Kaplan and Chris Ridenhour at Evolution Management, and Darren Trattner at Jackoway Tyerman Wertheimer Austen Mandelbaum & Morris.
Summit Entertainment plans to release 10 to 12 films each year.
