George O’ Hanlon(the voice of George Jetson) was in ill health and struggled to finish his work on the movie. Mel Blanc(Mr. Spacely) also died during the making of the film. John Debney wrote a lush, epic music score for the film and he adapts Hoyt Curtin’s Jetsons theme song. The film blends 2D animation with decent, 1990’s style CGI.
