Actor Daniel Radcliffe got his start as the titular lead in the 'Harry Potter' film series but his experience gave him much more than just fame and fortune. In the years since the final film in the series Radcliffe maintained a close relationship with his co star Alan Rickman. Rickman, a two time Tony nominee himself, even came to support Radcliffe in his Broadway theater ventures including 'How To Succeed in Business Without Really Trying' ('H2$') and 'Equus.' Rickman passed away early Thursday after a battle with cancer. In the wake of his death Radcliffe has pinned a touching essay obit about his friend.
