While The Return of Jafar wasn't Disney's first sequel, it was the first direct-to-video sequel that helped legitimise the DTV market (and launch the rest of the sequels on this list). Serving as the pilot to the Aladdin TV series, The Return of Jafar takes place a year after the movie. When thief Abis Mal (Jason Alexander) releases Jafar (Jonathan Freeman) and Iago (Gilbert Gottfried) from the lamp, it's up to Aladdin (Scott Weinger) and friends to stop Jafar from taking over the world.
Although there's a glaring lack of Robin Williams (due to issues with marketing of the first movie he opted not to return), The Return of Jafar is still whimsically fun as we get to see more into the lives of Aladdin, Jasmine (Linda Larkin), and Genie (Dan Castellaneta). There are also a few iconic music moments, like Jafar's "You're Only Second Rate" and Iago's "I'm Looking Out For Me." Plus, we get to see how Iago went from villain sidekick to wise-cracking good guy.
The Return of Jafar is currently available to watch on Disney+.
