Al Pacino's latest co-star is to be entirely computer-generated, it was revealed last week.

The pixelated prima donna is to be created after a series of actresses failed to win over casting staff working on Simone, Pacino's latest film.

The actress will star opposite Pacino, who plays a Hollywood film producer in the project, which centres on a young woman who becomes a movie star overnight and how it changes her life.

The move has been a blow to agents used to taking ten per cent of the revenues of film stars.

Computer animations have become increasingly popular as co-stars.

The Phantom Menace, the latest Star Wars movie, relied heavily on such graphics.
