I'm not too familiar with the original story. But this is a well done anime movie.
Puss n Boots is about a cat name Pero who was given a death sentence for not eating a mouse. He runs away while 3 cat killers are on his trail.
On the run Pero finds a small cottage with 3 boys. There are 2 older ones who don't give their youngest brother a brake. That young boy is name Pierre who very simple minded. After Pierre finds out that his brothers are not being honest on their share of money. They kicked him out.
Pero cheers him up and tells him that he has a hunch that he could make Pierre's life a lot easier.
So they head for town and heard the news that the King is searching for a rich prince to be wed with his daughter, Princess Rose. Pero finds this the right opportunity. So he must make Pierre look like a prince. But Pierre doesn't find it a good idea to live a lie.
Meanwhile an Orge named Lucifer demands that he married the princess. But Rose didn't find him the right "man" to be with. Lucifer didn't take no for an answer. So he gave the king 3 days to decide. Other wise the kingdom will face catastrophic measures.
Pero tells the King that Pierre will fight Lucifer. But Pierre doesn't find that possible to achieve. Pero however has confidants in Pierre. So how will Pierre save Rose from Lucifer? Puss N Boots is a very old anime movie. Way back when early Japanese cartoonists were inspired by Disney Cartoons to make their own. This one is Disney like only the quality is different from what you'd find in an American cartoon.
The cool thing is the chase scenes were animated by THE Hayao Miyazaki who was a key Animator back then. And this movie is the debut of Toei's mascot Pero himself.
Overrall, it's a highly acclaim classic for all time anime fans or those who like older anime. It's perfectly fine for kids to watch too. You only see once small scene of Pierre's rear end.
If you like this one I also recommend "Animal Treasure Island" which was also done by the same people who made Puss n Boots possible.
