'Play it Again, Sam' trivia and fun facts

First of eight cinema movie collaborations of Woody Allen and actress Diane Keaton.

With the assistance of director Herbert Ross, Woody Allen adapted his "Play It Again, Sam" play for this film version in only about ten days.

The film's tagline "Here's laughing at you kid" was a spoof of the famous Humphrey Bogart line "Here's looking at you kid" from 'Casablanca'.

Hollywood legend Humphrey Bogart never actually said the phrase "Play it again, Sam" in the film 'Casablanca', although everybody thinks so due to the tittle of this movie.
