The movie, to be released on Friday in the United States, is Disney’s first based on Marvel comic book characters since it bought Marvel Entertainment Inc. in 2009.
Set in fictional San Fransokyo, the Japanese-themed film tells the story of young Hiro Hamada, a robot-obsessed nerd who is devastated when his older brother Tadashi dies in an accident.
Baymax is the inflatable robot Tadashi was working on before his death. He is designed to care for sick humans, which he promptly does for the depressed teenager.
Along with six friends, Hiro and Bymax embark on a dangerous mission to hunt down the thief who stole Hiro’s latest creation: tiny microbots which can form themselves into any shape and be controlled telepathically.
