Global Heresy (alternately titled Rock My World in the United States and Canada)[2] is a 2002 comedy-drama film directed by Sidney J. Furie, and starring Peter O'Toole, Joan Plowright, Alicia Silverstone and Martin Clunes.

The film centers on a highly successful American rock band recovering from the loss of their leader by going into seclusion in the United Kingdom.

They rent a mansion from an aristocratic couple, Lord (Peter O'Toole) and Lady Foxley (Joan Plowright), who are in need of money.

When the staff hired to be on hand when the band arrives do not show, the couple decides to act as the butler, Benson, and the cook, Margaret.

Towards the end of the film, the status quo becomes further shaken when the original band leader shows up and admits that his disappearance had been a planned publicity stunt.
