VIDEO : Bradley Cooper Applauds Sienna Miller For Fighting For Better Wage

Bradley Cooper has stepped into the ongoing Hollywood debate over equal wages by saluting his ?American Sniper? co-star Sienna Miller for standing firm and pulling out of a play over poor pay.

The Brit was promoting the pair?s new movie, ?Burnt,? when she revealed she quit a theatrical venture after discovering her male co-star was earning more than she was.

She explained, ?I walked away from a play that I wanted to do because I was offered less than half of what the other man was offered and it was just the two of us. I did what we (women) have to start doing, unfortunately, at the expense of our creative dreams.?
