23. 'The Blues Brothers'
At the exact same time that Saturday Night Live was going through a major period of rebuilding after the departure of Lorne Michaels and the entire original cast, one of the show's most enduring sketches made the transition to the big screen. The Blues Brothers is the tale of Jake and Elwood Blues trying to save the orphanage where they were raised, but it's also a great comedy and a musical. That's a tough fusion to pull off (as proven by the disastrous sequel), but pull it off they did.
