Questions about the Walt Disney animated Movie Hercules.

I have some Questions about the Walt Disney animated Movie Hercules:

1- Was the movie inspired by Greek Mythology or ancient Greek religion ?

2- Did the Kingdom Hearts video game series use the same characters

in the movie ?

3- Did the movie had any sequels or TV series ?

@mister_x_1:

1. Ancient Greek Mythology
2. Yes but not always the same voice actors.
3. Indeed, Hercules The Animated Series. It was a prequel to the film rather than a sequel. I thought it was a pretty decent show IMO. No sequel though.
