Deliberate mistake: It's not possible for Chance to have been able to launch the cougar off the cliff with just his own weight.
Homeward Bound (1993)
1 deliberate mistake
Directed by: Duwayne Dunham
Starring: Michael J. Fox, Sally Field, Anne Christianson, Don Alder, Ed Bernard, Kevin Chevalia
Continuity mistake: After failing to catch Sassy, who went down the waterfall, Shadow and Chance are walking by the river bank. In one shot, Shadow's fur is wet, then dry, then wet again.
Chance: Cats are smarter than dogs, huh? Right. She doesn't even know the meaning of the word, "stay."
Trivia: When Chance jumps out of the car, he bangs the youngest child's head on the door hard enough to make the camera pan off him pretty fast.
