Boris and Natasha: The Movie (1992)
Boris and Natasha: The Movie is a 1992 comedy film that was loosely based on the animated television series The Rocky and Bullwinkle Show. It was shot in New York City. The actors did not attempt to copy the accents of their animated counterparts, and although Rocky and Bullwinkle do not appear in this film, they are referred to by the names "Agent Moose" and "Agent Squirrel". This was due to the production company's inability to secure the rights to the animated characters' likenesses for this film. Originally intended for a theatrical release, this film was produced by Management Company Entertainment Group for Showtime Networks, and aired on Showtime on April 17, 1992.
