"The Postman Always Rings Twice"(?)
From the imdb trivia section on the 1994 Alec Baldwin/Kim Basinger vehicle "The Getaway":
BEGIN:
When (Basinger) is driving the car and (Baldwin) is shooting from the back seat, a spent cartridge ejected from the gun hit Kim Basinger on the lip. Filming stopped for over a week while the wound healed.
