Dr Malcolm Crowe (Bruce Willis)
Look, if you've never seen the movie or haven't heard what the big twist is… um… you've probably already been spoiled just by looking at this page. But the film is 10 years old, people!
Anyhoo, Willis gives a suitably haunted (yes, pun intended) performance as Crowe, trying to help disturbed youngster Haley Joel Osment, who sees, say it with us, "dead people."
Crowe helps him realise that Osment's Cole Sear can help the recently departed, including a girl whose mother was poisoning her. The big twist is, of course, that Crowe is also dead and must slowly come to terms with the fact he has to give up his old life…
While circling a passage in his notes, Willis uses his right hand. He's actually left-handed and learned how to write right-handed so that cinemagoers wouldn't notice that his wedding band was no longer on his hand. Dedication!
