Earthquake (1974)

Continuity mistake: In the office tower after the quake there is a panic and workers rush down the stairs only to find them fallen away. After two women fall to their death a man is left hanging on a girder, but falls onto a giant piece of glass. Look at the top of the frame and you will see the airbag shooting our from under it.

Sam Royce: Barbara, take off your pantyhose, damnit! You too, c'mon, take off your pantyhose.

Trivia: Walter Matthau plays the drunk who sits at the bar wearing a loud shirt and pimp hat. However, for the end credits his name is listed as "Walter Matuschanskayasky"
