"Bart of Darkness" is the first episode of The Simpsons' sixth season, which originally aired September 4, 1994. It was written by Dan McGrath, and directed by Jim Reardon. In the episode, Bart breaks his leg; his resultant isolation causes him to believe that Ned Flanders has committed murder. The episode was produced during the 1994 Northridge earthquake which held up production by a month, and is largely a parody of the film Rear Window.
