Okay, it should be understood that while the script of this film is fantastic and basically flawless (most of the comedy comes from the one-liner sexual innuendos), much of this movie's greatness is due to the talent of the actors. Marilyn Monroe, Tony Curtis, and Jack Lemmon do a superb job of interpreting the screenplay, so much so that you really can't envision this movie being done with any other cast. So, a great lesson in screenplay adaptation is to read the screenplay and then watch the movie. You will see how talented actors, with good chemistry, can really bring a script to life...and make a great script even better. A true classic.
