Is that true??
"Beam me up, Scotty!" is a catch phrase that made its way into pop culture from the television series Star Trek. It comes from the command Captain Kirk gives his transporter chief, Montgomery "Scotty" Scott, when he needs to transport back to the ship.
Ironically, Kirk has never actually said "Beam me up, Scotty" in any Star Trek television episode or film. He comes closest in Star Trek IV, saying "Scotty, beam me up"; in Star Trek: Generations, saying "Beam them out of there, Scotty"; and in the animated episode "The Infinite Vulcan", saying "Beam us up, Scotty". The phrase was popularized by a bumper sticker with the tag line "Beam me up Scotty. There's no intelligent life here".
It is also true that the phrase "play it again, Sam" was never uttered in the movie Casablanca.
