A formula for boffo box office?

A British academic believes she has found the holy grail that all Hollywood seeks: the recipe for making box-office hits time after time.

Sue Clayton, a lecturer in screenwriting and directing at London University, said she analyzed “frame by frame what elements were present in different film genres and what made certain films successful.”

According to Clayton, the blueprint for the perfect film is for it to have 30% action, 17% comedy, 13% good versus evil, 12% sex/romance, 10% special effects, 10% plot and 8% music.

The study was based on breaking down the components of a range of hits, from Brit-flicks “The Full Monty” and “Notting Hill” to U.S. blockbusters such as “Die Another Day” and “Titanic.” The film that matched the recipe closest was “Toy Story 2.”
