George Lucas is so desperate to enlist Sean Connery in the new Indiana Jones film, he's written him into the script without the actor yet agreeing to appear in the movie.

Lucas, who has secured Harrison Ford, Cate Blanchett and Shia Labeouf for the series' fourth installment, is willing to rewrite the story if Connery refuses to reprise his role from 1989’s Indiana Jones and the Last Crusade but is hoping he can convince the actor to star in the much-anticipated sequel.

Lucas, 62, says, "We have a script with him in it.

"If he doesn't do it, we'll do a quick rewrite."

Rumors of Connery's return as the fictional adventurer's father, Henry Jones, have been rife since the film went into pre-production in January.
