Robert Downey Jr may quit `Gravity`

Los Angeles: Robert Downey Jr is likely to opt out of director Alfonso Cuaron`s movie `Gravity` due to a scheduling conflict.

The actor was supposed to film "Gravity" before he shoots "Sherlock Holmes 2". But a long casting process for the lead actress has delayed the production, and now Downey has already filmed the "Sherlock Holmes" sequel, reports

According to, these delays "have taken a toll on Downey, who needs to focus soon on `The Avengers`, and then `Iron Man 3`". He has also been roped in to star in "Oz: The Great and Powerful" as well as "Yucatan".

However, Warner Bros is denying rumours about Downey`s exit, claiming they expect to work out the scheduling problems. Meanwhile, the film`s lead actress Sandra Bullock is also reportedly trying to ask him to stay.
