it pays the bills

From Wiki:
"The original cast for the film included Joan Rivers in Bobcat Goldthwait's role. Elliot Gould was the original voice of the horse. After a poor test screening of the film, the horse's half of the script was rewritten by future Monk creator and executive producer Andy Breckman in an effort to make the film funnier. John Candy was hired to re-record the horse's voice; he ignored the new script and improvised the dialogue instead."

Tim Burton was also slated to direct.

The talking horse is much more believable than the idea that anyone could be in the same room with Bobcat Godlwait for five minutes without punching him.

I am shocked and disturbed that there is anyone alive who is unaware of this movie.

9 year old me ADORED this movie. I wore the tape out. This and "An American Tail".

Costarring with an animal was a pretty big thing in the 90s. I remember my dad taking me out of a number of those damned movies.
