It’s the 25th anniversary of Back to the Future, and the filmmakers celebrated it with a special DVD release last month. For all the fans out there, you might remember that Pepsi was a favorite drink of Marty’s in the films, from getting yelled at for wanting free Pepsi (Pepsi Free) at a diner in 1955, to ordering a Pepsi Perfect in 2015. Here’s some photos from the cast’s reunion on “Good Morning America.” We also found this really fun Facebook group dedicated to the reference “I’d like a Pepsi Perfect Please!”
