2. 'Blues Brothers' (1980)
Based off the popular Saturday Night Live sketch and band of the same name, Dan Aykroyd and John Belushi took their Blues Brothers act to the big screen, spawning a cult classic. In the film, "Joliet" Jake Blues (Belushi) and Elwood Blues (Akroyd) set out to save the orphanage they were raised in after Jake is paroled from prison. To raise the money, they host a benefit concert and, along the way, receive help from the likes of Aretha Franklin, Cab Calloway, Ray Charles – who all sing in the film as well.
