Morgan Freeman has donated $1 million to Barack Obama's re-election campaign.

The Dark Knight Rises actor joins the likes of Bill Maher and DreamWorks Animation CEO Jeffery Katzenberg in delivering millions of dollars to the operation, and Morgan has praised the Democrat president's history of working on "tolerance."

"He ended combat operations in Iraq, put in place sensible reforms of Wall Street, saved the auto industry and protected the health care of every American. He has led our nation to be more tolerant and placed impressive, accomplished women on the Supreme Court. In return, he is the target of hundreds of millions of dollars from right-wing sources. I am proud to lend my voice - and support - to those who defend him. Priorities USA Action is doing a great job of protecting the values I believe in. I am happy to help them and I hope others will join me."
