Johnny Depp is poised to replace tragic Heath Ledger in his latest film role, reports UK's The Sun.

Heath, who was found dead Tuesday in New York, was six weeks away from finishing fantasy flick The Imaginarium of Doctor Parnassus.

Now director Terry Gilliman wants his pal Johnny to film the remaining scenes.

A studio source said: "There is a point in the film when Heath falls through a magic mirror. He could change into another character after that and that is where Johnny would come in.

"It's a weird, fantasy, time-travel movie so Heath's character could easily change appearance. It would be a poignant moment.

"Johnny's not working at the moment so everyone is praying he will do it."
