Something's Rotten

Something's Rotten is a Canadian drama film, directed by Harvey Frost and released in 1979. The film stars Charlotte Blunt as the queen of an unnamed European country, who is being pressured by the Prime Minister to abdicate the throne in favour of one of her sons, but who must wrestle with the question of which son, the older but emotionally unstable Prince Calvin or the younger but more mature Prince George, will be named as her successor. Meanwhile, a series of murders of the palace staff is being committed by an unidentified "Skulker", whom the queen begins to suspect may in fact be one of the princes.
