I think the best movie in the world would be a WE LOVE KATAMARI movie titled OMG!!! KATAMARI!!!! It would star Bruce Lee on speed as the KATAMARI and Will Ferel as a man seperated from his wife and kids when they get rolled into the Katamari and has to fight his way through the Katamari to find his wife and kids.
On the way he encounters and fights pirates, ninjas rofflcopters, computers, tuesday, a family guy dvd, the dresden dolls, a smiling chimpanzee, tiananmen square, everyone in the entire world, and some bread.
When he reaches his wife and kids he finds out they are kidnapped by space banditos and the only way he can get them back is if he fights his way to the centre of the KATAMRI and have to kill PRINCE to unroll th eKATAMARI.
THEN everyone dies 'cos its true.
