Understood to be his last work, as it was incomplete when he died, the trailer for The Imaginarium of Doctor Parnassus looks so cool. I think the best part of the movie seems to be the replacements. With scenes incomplete, and they wanted to finish the film; and they did. But it seems that they DIDN'T try to fake it. Although, it's not all Heath in the film, you can clearly tell that it is Colin Farrell, Jude Law and Johnny Depp that fill in his role. To me it always seems cheesy when they try to sneak it by you with editing and camera tricks so nobody knows. Based on the trailer anyway, seems like a classy move in Hollywood for once.
