Tom Cruise, Christopher Walken, Robin Williams, Brad Pitt, Tigger and the Teenage Mutant Ninja Turtles have teamed up for this Uptown Funk cover.

Mark Ronson’s Uptown Funk has inspired no shortage of viral videos, but this latest bit of magic comes courtesy of YouTube user dondrapersayswhat, who spent three months combining clips from 280 movies for this mashup.

The finished product includes blink-and-you’ll-miss-it scenes from Back To The Future, The Terminator, Groundhog Day, Shrek, Napoleon Dynamite, Wedding Crashers, Pretty In Pink, Finding Nemo and more. MVP honours have to go to Tropic Thunder‘s Robert Downey Jr, who helps out with that key ‘Hot damn!’ lyric.

Needless to say, it’s a must-watch, and here’s a tip — if you need help identifying the 280 films, turn on Closed Captioning.
