It started out as a joke, but Mark Webber's plans to contest the Bathurst 12-hour endurance race with Hollywood movie star Eric Bana are starting to get serious.
Webber sparked plenty of interest last week when he responded to a fan's tweet, asking whether he was going to drive for Porsche with fellow Australian Bana at next year's event at Mt Panorama.
The newly retired Formula One driver replied: "No 2015".
Bana, in Sydney to promote his new film Closed Circuit, said nothing was set in stone but was hopeful of making it a reality.
"It started out as a bit of a joke and then it's kind of taken off, so obviously I'd be thrilled to," said Bana. "I was testing a car for this year's 12-hour - which is coming up in February - and tweeted a photo of the car that we might be driving. Mark follows me on Twitter and immediately tweets something like 'we'll have to get you out of that car and into a different car and we'll do the 12-hour together'.
