I didn't really know a lot about Robert Downey Jr until he was on Ally McBeal. I remember him being in all the papers about his addiction problems at the time. I was a big fan of Ally McBeal and his character was just the perfect fit on that show. Then Downey got arrested (I believe for drug problems) and Fox demanded he be written off the show. Then Ally McBeal went down hill from there.
I'm glad he seems to have overcome his addiction problems. I love the characters he plays and wish him much success.
