This morning in St Kilda, Stevens discovered his car window broken, and camera equipment along with a hard drive containing hours of interviews for the documentary were stolen.

“You’d look at the hard drive and you probably wouldn’t know what’s on it,” he said.

“There’s stuff on there about stories no-one’s ever seen and stuff on there they were only willing to tell to us.”

The large black and silver hard drive contained narratives that Stevens intended to use to inspire those dealing with head injuries after concussions forced him to retire from his AFL career, and it was stolen along with camera gear worth tens of thousands of dollars.

“Doctors, athletes who were going on their own healing journeys. Myself and Eric Bana have been shooting that story for the last five years,” Stevens said.

When he finished with St Kilda, head knocks meant Stevens couldn’t get out of bed. 

But today as he was about to head off on a shoot, he had just gone upstairs, returning to find the smashed glass in St Kilda. 

“You wouldn’t think something like that would happen so quick,” Stevens said.

Despite multiple CCTV cameras on the street, police believe they may have missed the actual theft.

All Stevens wants is the hard drive back.

“If anyone comes across it, I don’t even care about the camera equipment, just drop the hard drive off,” he said.

The film Thrive is due to enter post-production at the end of the year. 

“The film’s pretty game-changing and on that hard drive was some pretty game-changing stuff,” Stevens said.

“It’s just the sensitive nature of it all, that’s now floating around in Melbourne somewhere.”
