14. Robert Downey Jr. In I Want Love - Elton John

In 2001, Robert Downey Jr. was still struggling with personal demons and hadn't yet reached the superstar levels he would once he took on the role of Tony Stark/Iron Man. Yet he was still enough of a star to be cast in the only role for Elton John's I Want Love video. The entire video is a single shot following Downey as he lip-synchs the song inside Greystone Manson in Beverly Hills, CA. It was directed by Sam Taylor-Johnson, who you now know as the director of Fifty Shades of Grey.
