Australian NBA superstar Ben Simmons has jumped on board with a new documentary about Adam Goodes to ensure the story of the AFL great's battle with racism will be spread around the world.

Simmons has become an executive producer of The Australian Dream, which will premiere next week at the Melbourne International Film Festival and includes fresh interviews with Goodes about the sad end to his career with the Sydney Swans.

A passionate AFL fan and Essendon diehard, Simmons has chosen to lend the heft of his international profile to the film after discussions between producer John Battsek and Uninterrupted - a multimedia company and 'athlete empowerment brand' founded by LeBron James and Maverick Carter which Simmons is associated with - brought it to his attention.

"We were talking about projects we might collaborate on. When I mentioned this to them they immediately identified it as one they thought would appeal to Ben," Battsek said.
