LONDON(BBC): A film producer has won a High Court case against the surviving members of Monty Python over royalty rights to the hit stage show, Spamalot. Mark Forstater, who produced the 1975 film Monty Python And The Holy Grail, claimed he was underpaid royalties since the musical’s launch in 2005. He estimated he was entitled to more than £200,000.Three stars of the cult Python film - Eric Idle, Michael Palin and Terry Jones - gave evidence at the trial. Written by Eric Idle, hit musical Spamalot was described on posters as being “lovingly ripped off” from the 1975 film Holy Grail.
