Chris Hemsworth is giving you a chance to attend the world premiere of Avengers: Infinity War. He’ll also meet you there for photos and autographs, if you’re into that sort of thing.

Hemsworth is doing this to encourage donations to the Australian Childhood Foundation. It only takes $10 to enter, so you should take a chance and support some kids!

You can enter here.

Avengers: Infinity War is in theaters April 27.
