Trivia: As already noted, Hercules wears a lionskin which is made out of Scar. In the myths of Hercules one of his great tasks was to kill a vicious lions and he kept the skin ever since. But it's more than just a joke or a cameo that he wears Scar, for both Scar and Hercules were animated by the same man (Andreas Deja).
Trivia: During the scene when Hercules is being painted with the (previously mentioned) Scar carpet on, Phil is telling Hercules about his schedule for the day. Listen to what he says. He mentions some of Hercules' other 12 tasks found in Greek mythology, like stealing the belt from the Amazons.
