Mark Ruffalo made an Aussie fan's day by jumping into his car and announcing: "I'm the Hulk".

The star is on the Gold Coast filming Taika Waititi's Thor: Ragnarok, and went out for a few drinks with the cast on Saturday. Afterwards, he ordered an Uber.

That was when 21-year-old Mitch Hesse picked him up and, without realising who was in his back seat, asked what Ruffalo did for work.

His response? "I'm the Hulk."

"I turned around in disbelief, I was so excited he was in my car," Hesse told Confidential.

"He was a top, genuine bloke. He said he could see himself moving here, he loves it."

Hesse posted the snap to Facebook writing: "I work as an Uber driver and last night I randomly picked up the movie star Mark Ruffalo ... and it was so awesome! Does that mean I'm famous now?"

If so, he's in good company. Ruffalo's clearly a fan of Uber, and there are a tonne of other big stars in town for the film, including Chris Hemsworth, Cate Blanchett, Anthony Hopkins, Idris Elba and Jeff Goldblum.

And of course, Thor villain Tom Hiddleston will be in town, perhaps with his new love interest Taylor Swift.
