This week marks the 50th anniversary of the Disney animated classic '101 Dalmatians.'

If you've somehow forgotten, the 1961 movie focuses on Pongo and Perdita, two proud Dalmatian parents, and their search for their 15 puppies, who have been kidnapped by the nasty Cruella De Vil.

De Vil wants to skin the dogs for her luxurious new fur coat but gets no help from her bumbling sidekicks, Jasper and Horace. Along their adventure, Pongo and Perdy team up with a countryside full of farm animals, rescue 84 additional stray Dalmatian pups, and return to the home of their owners, the Radcliffes, with a family in the triple digits.

You may think you know everything about the beloved family film, but did you know about the dogs' alien adventures or their connection to the rock band Styx? With sequels, TV shows, remakes and a stage show under its belt, '101 Dalmatians' has amassed a long and impressive history, full of surprising nuggets of trivia.

In celebration of the film's 50th anniversary, we present you with 101 things you didn't know about '101 Dalmatians.' But first, refresh your memory by watching a trailer for the classic movie.
