Mark Ruffalo believes in human decency after his lost wallet was returned safely to him.
Mark Ruffalo believes in the ''decency in people'' after his wallet was returned to him.
The 46-year-old actor - who stars in new feel-good film, 'Begin Again' - left his wallet in a cab in Chicago but it was returned thanks to the power of social media when a stranger contacted the star to reunite him with his lost item on Twitter.
They tweeted: ''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.''
The actor took a few days to see the message but he was quick to tweet back his thanks when he found out.
He said: ''Thank you! Wow! Another point for the decency in people.''
Mark - who also stars as The Hulk in 'The Avengers' movies - reportedly exchanged a few direct messages with the person through the social networking website to arrange the wallet's return.
The actor later said of the good Samaritan: ''You are a hero!''
Meanwhile, Mark recently admitted he would be interested in appearing in a movie about the Hulk.
He said: ''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 [Bruce] Banner and The Hulk as a conscious conflict, it could be really interesting.''
