In his research and preparation for playing Bela Lugosi in Ed Wood (1994), the biopic of cult director Edward D. Wood Jr., Martin Landau watched this film three times stunned, saying that it was so bad "it made the Ed Wood films look like Gone with the Wind (1939)".
This is the only known existing filmed record showing Duke Mitchell and Sammy Petrillo doing their act, which was a blatant imitation of Dean Martin and Jerry Lewis (Lewis, in fact, later sued Petrillo for copying his act so closely).
Bela Lugosi's name never appears in the credits in the version of the movie that uses the "Boys from Brooklyn" title screen. Presumably the original title of "Bela Lugosi Meets a Brooklyn Gorilla" made a listing in the credits unnecessary, but since that was the only place his name appeared, the title change meant that his name disappeared completely from the credits, as there are no cast credits at the end of the movie either.
Filmed in nine days on a budget of $50,000.
