Tourism Queensland and Nine's Today show have teamed to give one punter a walk-on role in the Taika Waititi's Thor: Ragnarok.
In addition, Premier Annastacia Palaszczuk said the winner would receive backstage access and a Gold Coast holiday with three friends.
"Being part of a Marvel Studios production is a unique opportunity and I am proud my Government was able to secure the filming of this blockbuster for our state," Ms Palaszczuk said.
"The winner will see the making of a Hollywood blockbuster and the brand new super stage, the largest of its kind in the southern hemisphere, which the Government invested in and is being used for the very first time for this movie."
"This promotion and working with studios such as Marvel to ensure Thor was exclusively filmed in Queensland is a great opportunity to showcase our state and boost the economy."
