The only difference in the opening intro is that when the "Heathcliff" logo appears on-screen, Heathcliff stamps text that says "THE MOVIE" next to the logo.
Cleo, Riff-Raff, Hector, Wordsworth, Mungo and the rest of the gang had not appeared in this movie.
Some of the music in the segments are different from the TV versions.
The movie's end credits are also very similar to the show's end credits.
This movie was produced in 1985, according to the copyright stamp at the end of the closing credits.
