Sandra Bullock and Tom Hanks are being eyed for starring roles in the feature version of post-9/11 drama Extremely Loud and Incredibly Close with Scott Rudin producing for Warner Bros. and Paramount.

According to Variety, Warner Bros. indicated it has sent out offers to Sandra Bullock and Tom Hanks but no formal negotiations have been reached.

Set in 2003, based on the Jonathan Safran Foer novel, the story centers on a 9-year-old boy who finds a key in a vase that belongs to his father -- who perished in the Sept. 11 terrorist attacks -- and searches to find the lock that goes with it. It was one of the first American novels to incorporate the Sept. 11 events into the plot.

Scott Rudin has been developing the project since 2005, when Extremely Loud and Incredibly Close was published. Eric Roth has adapted the novel and Stephen Daldry is attached to direct.
