Before Yeardley Smith was known as the voice of Lisa Simpson on “The Simpsons,” she starred in the movie “Maximum Overdrive.” The 1986 film was written and directed by Stephen King. Smith tells Yahoo Entertainment that King, “Could not have been nicer and he was incredibly humble.” She does admit that he was struggling with a few challenges: an all-Italian crew, a language barrier and his own drug addiction. King has claimed that he was “coked out of my mind” during the production of “Maximum Overdrive.” “I do remember … he would just start drinking,” Smith recalls. She also remembers one particular scene where a car drives through a truck stop and she has to scream on cue. “That car came so fast,” Smith says. “That scream is so real.” Watch the video above for more with Yeardley Smith.
