The director Terry Gilliam decided to keep Heath in the film, but supplement his role by having Johnny Depp, Colin Farrell, and Jude Law play parts of the role as well.
The movie is about Dr. Parnassus and his extraordinary 'Imaginarium', a traveling show where members of the audience get to choose between light and joy or darkness and gloom.
One thousand years ago, Parnassus made a deal with the devil, Mr Nick, in which he won immortality. Many centuries later, on meeting his one true love, Dr Parnassus made another deal with the devil, trading his immortality for youth, on condition that when his first-born reached its 16th birthday he or she would become the property of Mr Nick. Valentina is soon approaching her 16th birthday, and Dr Parnassus is desperate to protect her from her impending fate. Mr Nick arrives to collect but, always keen to make a bet, renegotiates the wager. Now the winner of Valentina will be determined by whoever seduces the first five souls. Enlisting a series of wild, comical and compelling characters in his journey, Dr Parnassus promises his daughter's hand in marriage to the man that helps him win.
