This fun video supercut comes from supercutonline, and it features dancing scenes from different classic films. Here's some information on the video:
"Dancing on the silver screen has been happening since film was invented. From the big time musicals to the small quirky dances that pop up now and then. There are so many examples of dancing we could only fit 246 films in this cut, so a part 2 might be on its way for the 100+ clips we had left over. We hope you enjoy it as much as we've had making it and the Bee Gee's 'You Should Be Dancing' never gets old."
