Marvel Studios is giving Queenslanders a peek behind its warehouse doors in a new exhibition at the Gallery of Modern Art, displaying more than 500 costumes, sets and props from its many films.

Opening on Saturday, the Marvel: Creating the Cinematic Universe exhibition is the largest Marvel exhibit ever staged and includes set pieces from Thor: Ragnarok as well as objects never seen by the public before.

Marvel's physical production manager Alexis Auditore said the movie studio was excited to be part of the large exhibition.

"We're showcasing a lot of props and costumes that have never actually been seen by the public," she said.
