"I found an old hard drive with a bunch of BTS shots from Bill & Ted 1. These are from the opening dance number (yes an actual, choreographed rock jam) and face off with the jocks at the bus stop that didn’t make it into the movie," Winter tweeted.

The pictures mainly show the two stars, Winter and Keanu Reeves, goofing around behind the scenes of the 1989 cult classic, although one heartwarming shot features the late George Carlin, who played supreme being Rufus.

The third film in the series, Bill & Ted Face the Music, from Orion Pictures, is due in theaters Aug. 21.

Check out some Winter's photos below.
