Deadly movie by Terrence Malik, Badlands (1973) starring Martin Sheen, Sissy Spacek among others.
It is loosely based on the true crime spree by Charles Starkweather and his girlfriend Caril Ann Fugate in 1958. This one is more or less the same. Kit (Martin Sheen) is a garbage pick up worker and Holly Sargis (Sissy Spacek) a 15 year old girl in South Dakota living with her father.
Kit meets Holly and falls in love with her instantly. He meets up with her father and asks for favours. The old man refuses to have anything to do with him and tells him off. He returns later and kills her dad and they burn the house to look like an accident. Both Kit and Holly escape and their spree starts there, killing so many people wantonly.
Lot of rides later they end up in Montana and a deadly car chase follows in which Kit is caught, after Holly goes with the police. Dramatization of the story is quite superb, with awesome photography and cinematography, this one is a cult classic.
Both Martin Sheen and Sissy Spacek lend credence to their roles quite admirably. Sissy Spacek lends her voice over to her part in the movie. Holly had his own sense of self importance in the world like the murders were a show off for his talents. In the end he gives away his various things like pen, and comb as souvenirs to the police officers.
Terrence Malik has kept the interest alive in the movie through his taut direction.
