1973 The Legend of Hell House. A millionaire buys an old house and wants to evict the houses long time only resident, who just happens to an an evil spirit that is haunting it. The ghost of the man who built the house, (Emrick Belasco) who was evil when he was alive.

4 people are sent to rid the house of its ghost. A Physical Medium. A Mental Medium and a physicist that uses technology to get it done, who also brings along his beautiful lonely wife, just dying for affection, wonderfully played by Gayle Hunnicut. Roddy McDowall plays the Physical medium, who happens to be the only survivor of the last party thrown by the ghost haunting the house.

When Gayle Hunnicut asks Roddy McDowall what made Belasco so evil, he answers with great seriousness. "Drug Addiction. Alcoholism, Bestiality, mutilation, vampireism, necrophilia, cannibalism. Not to mention a gamut a sexual goodies. Shall I go on"?

"How did it end"? She responded.
"If it had ended" He said. "We wouldn't be here"

"Jaws"- Police chief Martin Brody after seeing the great white shark they are dealing with tells Captain Quint"You're gonna need a bigger boat" . Quint ignores that and they end up in a lot of trouble. I would say this is the line that makes this movie. It all boils down to Quint being stubborn and egotistical which in the end cost him his life.
