Both Michael Keaton and John de Lancie, who plays Ted, attended Kent State University in Ohio.

According to director Harold Ramis, he wrote much of the script uncredited. A Writers Guild rule prevents directors from getting a writing credit on their film unless they contribute more than 50 percent. Ramis contributed 40 percent of the screenplay.

In filming the shot in which Doug #1 introduces Doug #3 to Doug #2, Doug #2 tosses a beer to Doug #1. Michael Keaton catching the beer (tossed by a body double) was shot first. Keaton tossing the beer (this time *to* a body double) was filmed later. Keaton's toss so perfectly matched the body double's original toss, that the planned special effect of digitally erasing the tossed beer can then adding in a digital beer can was not needed, thereby saving the production quite a bit of money. This was referred to by the special effects crew as "The Million Dollar Miracle Beer Can Toss".

In the last scene that shows Doug #4 delivering pizzas on a bike, it is implied that he is delivering in Miami. Clear in the scenery are California Fan Palms. Although not as common in Florida as California, Fan Palms are still visible in some parts of Florida.

In the opening scenes, Doug and his wife repeatedly discuss whether or not he bought a "hot water heater". The correct term is simply water heater; hot water doesn't need to be heated.

The cereal box in Doug Kinney's hand changes between shots.

Doug Kinney #1: [to #2] I'll hit you so hard, I'll kill him!

Doug Kinney #1: No Clone Nookie Original Nookie Only!

Doug Kinney #2: [not happy about appearance of clone #3. Doug has promised to make it up to him] And you can start by cloning Laura!
