Terry Gilliam filming on Blackfriars Bridge

The film, due for release in 2009, stars Christopher Plummer and is described as a "fantastical morality tale set in the present day".

It tells the story of Dr Parnassus and his extraordinary 'Imaginarium', a travelling show where members of the audience get an irresistible opportunity to choose between light and joy or darkness and gloom.

The screenplay has been written by former Monty Python star Gilliam together with Charles McKeown.
