Sight gags.One liners.Nearly every one of them hitting the funny bone.That's what you have with Airplane! They picked a genre of films to poke fun of (Airline disaster films),they packed it chock full of one liners and sight gags,so many that if you blink,you are liable to miss a major laugh.The really genius move here by the makers of this film is casting it with actors that we had grown accustomed to taking seriously (Yes,Leslie Nielson was a serious actor for many years before doing this film).They mingled them with some pretty darn funny people and the result is nothing short of a comedy classic worthy of a spot on the DVD shelf.
