Mark Ruffalo had his lost wallet returned by a stranger who contacted him on Twitter.
The 46 year old actor, who played The Hulk in 'The Avengers', left his wallet in the back of a cab in Chicago, but was delighted it wasn't gone forever after a fan contacted him on the social networking site to say he had picked it up.
The good Samaritan tweeted to the star: "I have your wallet. Found it in a cab in Chicago on Friday. Let me know the best way to get it back to you. Thanks."
It took a couple of days for the actor to see the message, but he could barely contain his gratitude when he did respond.
He said: "Thank you! Wow! Another point for the decency in people."
The pair then reportedly exchanged a few direct messages on the social networking website to arrange the safe return of the wallet.
The 'Begin Again' actor later concluded: "You are a hero!"
Meanwhile, Mark recently expressed an interest in appearing in a Hulk solo movie, and he thinks it would be particularly fascinating to explore the conflict between his character Bruce Banner and his superhero alter ego.
He said recently: "It could get very boring to watch the guy who's moping around who doesn't want to do the very thing that we're all dying to see him do. And so I think that's the tough part of cracking that nut. I think that's what's made it problematical in the past. But I do feel like we've gained some ground on this new version of him, which has - he's sort of turning to face himself, and I think the relationship between Banner and The Hulk as a conscious conflict, it could be really interesting."
