"This is a true story" Ahahahahahahaha! Yes, true stories happen in slow-motion with green/blue filters all the time. But yes, it's loosely based on events reported in the Miami New Times, featuring characters who are considerably less likable than those usually played by Marky Mark and The Rock.
Here's the funny thing - Bay will probably get a lot less crap for taking liberties with the life stories of real people than he did for taking liberties with the designs of toy robots.
Maybe that's because Optimus was already likable.
Pain & Gain opens April 26th.
