This isn't the first time a Twitter user has come to Ruffalo's rescue. In July 2014, the actor left his wallet in a cab in Chicago and a man found it and tweeted at the Oscar nominee. "Thank you! Wow!" Ruffalo responded. "Another point for the decency in people…you are a hero!"
ET recently caught up with Ruffalo at the BAFTA Awards Season Tea Party, and he revealed that a particular Hollywood A-lister is in talks to join the cast of Thor: Ragnarok. Find out who in the video below.
