"Plaisir D'Amour" by Johann Martini, is sung by a chanteuse in the cabaret scene, but neither the song nor the singer are listed in the credits.

Julie Newmar (Catwoman in the TV series) does not appear in this film because she did not know about it and had signed to do another project. By the time she was informed, she could not get out of the other commitment in time to do this movie.

Reginald Denny's last movie.

Frank Gorshin's last appearance as The Riddler for well over a year. Gorshin sat out of the TV series during the show's entire second season, which preceded the film's release.

Adam West agreed to do the film partly with a stipulation to have more screen time as Bruce Wayne.

Lee Meriwether was Miss America in 1955.

A follow up film was at one point considered. The film would have been released between seasons two and three, and would have been used to introduce Barbara Gordon/Bat Girl, and make use of a Batplane. Due to waning interest in the series during season two, which resulted in budget cuts, plans for a second film were scratched.

As of 2010, this is the only live-action feature-length Batman film in which Alfred is not played by an actor named Michael. Michael Gough played the part in Batman, Batman Returns, Batman Forever, and Batman & Robin. Michael Caine took over for Batman Begins and The Dark Knight.

At the end of the film one of the delegates is seen banging his shoe on the table while yelling. This is a parody of Nikita Khrushchev's famous behavior during a debate in the United Nations General Assembly in 1960.

Bruce Wayne drives a Chrysler Imperial convertible, while the Batmoblie is a 1955 Lincoln Futura prototype car customized by George Barris Inc.

Dick Grayson appears outside of his Robin persona only twice and very briefly in the film. First, at the very beginning, and later when Bruce returns to Wayne Manor after being kidnapped. Dick's only spoken lines are in the latter scene.

During his date with Miss Kitka, Bruce quotes Edgar Allan Poe, the first stanza of "To One in Paradise".

Filming of the movie began before Lee Meriwether was cast for the movie. As a result, Catwoman does not appear with the other villains in the first scene aboard the Penguin's submarine.

First movie project of Burt Ward.

In the final fight scene, a stuntman playing one of the villains' henchmen dove into the water and hit his head on a metal stud at the bottom of the pond. He was knocked unconscious and had to be rushed to the hospital.

Inside joke: Burgess Meredith's line, "Run Silent, Run Deep" is the title of a 1958 submarine movie in which Frank Gorshin might have played a role had he been able to make it to the screen test.

Originally planned as the pilot film for the Batman TV series, the movie was instead produced between the show's first and second seasons. The producers took advantage of the larger budget to have a number of new Bat-gadgets constructed, such as the BatBoat.

Penguin's line "Everyone of them has a Mother" (said as he and Catwoman swept up and collected the dehydrated pirates) was ad-libbed by Burgess Meredith.

Scenes shot in the arch-criminals' headquarters lair were filmed at an angle. Rumors at the time were that this was intentional and was meant to show that the four (Catwoman, Penguin, Joker, and Riddler) were crooked.

The BatBoat was built especially for the film by the Glastron boat company. In exchange for their cooperation, the producers agreed to hold the film's world premiere in Austin, Texas, Glastron's headquarters.
