The Imaginarium of Dr. Parnassus

On Saturday I went to the movies to see "The Imaginarium of Dr. Parnassus".

Something weird regarding the making of the film is that the actor who played the main role, Heath Ledger, died during the shooting, and other actors like Johnny Depp, Colin Farrell and Jude Law finished the work.

Esthetically, it is worth watching. About the story... I am looking forward to hearing of somebody that can explain it to me. So, if you are reading this and has seen the film, please let me know the meaning of the two doors with the labels "His" and "Her". I would appreciate it so much.
