Trivia

This film was originally in pre-production since 1992, with Danny DeVito and Meryl Streep set to play Boris and Natasha. However, legal problems with copyrights prevented the film being made until several years later along with trying to find the right story that would be faithful to the original cartoon. Eventually in 1995, producer, Jane Rosenthal felt the movie should be a live action/animated hybrid movie thanks to the success of Casper (1995).

For the narration, Keith Scott is doing an imitation of the voice of the late William Conrad, who had been the narrator for the original The Bullwinkle Show (1959).

Rene Russo met June Foray at the film's table reading. By her own account, Russo was very nervous about taking on the role of Natasha Fatale and requested Foray to demonstrate the voice. Foray graciously obliged.

Robert De Niro said in an interview that he only did this film purely for the money.

Kenan Thompson and Kel Mitchell, a comedy duo of the mid 1990s, play Lewis and Martin, respectively. A nod to another comedy duo, Jerry Lewis and Dean Martin.
