The Godfather Part II (1974)
Most of the time, a movie's sequel is pretty subpar in comparison to the real thing. That is not the case with The Godfather! The second film in the franchise goes back in time showcasing the relationship between the Corleone father and son duo.
Apocalypse Now (1979)
This film is set in Vietnam in 1970. Martin Sheen and Marlon Brando star as two upper-ranked soldiers who are at odds and end with each other. Robert Duvall and Dennis Hopper also star in this iconic flick.
