David Rambo, the writer of 'CSI' and 'Revolution' is working with Permut Presentations and Reunion Pictures on the script of 'Tracy and Hepburn', reported Deadline.
The story would follow their relationship from their meeting at MGM during making of their first film together 'Woman of the Year' (1942) to Tracy's death in 1967.
Hepburn and Tracy were together for 26 years. Tracy died soon after shooting together for 'Guess Who's Coming to Dinner'.
During his affair with Hepburn, Tracy was still married to actress Louise Treadwell with whom he had two children. The couple hid their relationship from the public until Louise's death.
The couple have been portrayed in cinema in earlier instances too. In Martin Scorsese's 2004 film 'The Aviator' Kevin O'Rourke starred as Tracy and Cate Blanchett played Hepburn, a role for which she won an Oscar.
