15. 'The Blues Brothers'
Forever proving that moviae based off a Saturday Night Live skits can actually work, this 1980s classic lead Jake and Elwood Blues to go on a "mission from God" to save their former orphanage. Needless to say, it involves staging a massive concert. Everyone from Aretha Franklin to James Brown to Ray Charles appears in the film. As the 1980s went on, the movie slowly started playing at midnight screenings all across the country. A sequel was made in 1998, but the less said about that the better.
