Confessions of a Medium
Starring Bill Nighy as Thomson and Robert Glenister as Mr. Parker. A gothic, shadowy, and darkly comic drama about illusion, delusion and desire. Based on a true story in 1870's London. Mr. Parker is a sincere and kind man in search of a higher meaning to life. He has moved from conventional religion to séances and spiritualism. He believes he's met his saviour in the guise of Mr. Thomson - a charming, erudite, and utterly mesmerising medium, but unbeknown to Parker, Thomson is a complete and utter fake.
