Payton has a cameo in the film -- looks like he's playing a mechanic or something?!
As for the movie itself ... here's the backstory.
Payton received a 1-year suspension from the NFL in 2012 for Bountygate -- when Saints players were getting cash payouts from 2009 to 2011 for targeting and injuring opponents during games.
During his suspension, Payton coached his son's youth football team -- and reportedly used the time away from the league to "reassess his life and put it in some perspective."
The movie will focus on Payton's time away from his job -- and how he grew as a person because of the experience.
The movie is being produced by Adam Sandler's Happy Madison Productions -- so it seems the flick will be a lighthearted, family-friendly depiction of the situation ... despite the heavy and despicable nature of the suspension in the first place.
