Scarlett set for Indiana Jones 4?

Harrison Ford is set for a new sidekick when he returns to the big screen as Indiana Jones - in the shape of actress Scarlett Johansson.

Ton Cruise has been championing the Oscar nominee for a part in pal Steven Spielberg's fourth Indiana Jones movie as the pair work together on Armageddon drama The War of the Worlds.

Cruise has been working with Johansson on the third Mission: Impossible movie and he's convinced she'll be perfect for the new Jones film, according to Australia's NW Magazine.

An insider says: "Steven was saying there is a shortage of young actresses who can carry off a strong role. He considered Natalie Portman, but she's too connected with Star Wars - Tom suggested Scarlett."
