20 Things You Somehow Missed In Friday The 13th (1980)
7. The Godfather
Towards the opening of the film, the audience sees Jack Burrell, Marcie Stanler (Jeannine Taylor), and Ned Rubinstein (Mark Nelson) travelling to Camp Crystal Lake together in a pickup truck.
If viewers look closely, they will see a copy of Mario Puzo's highly successful 1969 novel, The Godfather on the truck's dashboard.
Of course, The Godfather had already been filmed by Francis Ford Coppola in 1972, leading to the creation of another well-remembered and financially successful movie franchise (although the critics were noticeably kinder to Coppola's work than they were to the Friday the 13th franchise).
