a film festival. Specifically, a one-night film festival where films are shown back-to-back beginning after dark and continuing until the sun comes up.
Generally, mainstream movies are not shown at bimfests. The movies should be old, obscure, odd, outrageous, or all of the above.
This week's bimfest will include Angry Red Planet, Bedtime for Bonzo, Muscle Beach Party, Hello Down There and Soylent Green.
