Buyers are abuzz at the casting attachments of Sandra Bullock and Ralph Fiennes to Renaissance Films' romantic fable Vapor which has been written and will be directed by Neil LaBute.

Set to start production in the second half of the year, the film is the story of a struggling actress who saves the life of a complete stranger - an eccentric scientist who makes her dreams come true.

Renaissance developed the project with LaBute and Gail Mutrux and is handling worldwide sales. Renaissance managing director Angus Finney is executive producing.
