The actor has denied multiple times that he is affected by the disorder.
So why the walk?
Apparently, he is just really passionate about Bipolar disorder.
He recently took to Twitter, his favorite method of communication, and asked fans to walk with him from his hotel to Toronto’s Massey Hall, where he performed for his "My Violent Torpedo of Truth" tour on Thursday, April 14 and Friday, April 15.
“Looking for all of you tonight at 6pm @ The Ritz to Walk to Massey w/me in support of Bipolar Awareness! I'm matching all donations $ for $,” the actor tweeted on Friday.
