And when ghosts raid your house..."Who you gonna call?"  The Ghostbusters, of course (1984).

Tom Hanks radios, "Houston, we have a problem..." and everyone is on edge watching to see if Apollo 13 (1995)  will land or burn through the stratosphere.

And of course, the famous prelude to a cosmic saga that has been parodied ad nauseam:  Star Wars' (1977) "A long time ago, in a galaxy far, far away..."
