Harrison Ford is moving from battling communists as Indiana Jones to fighting diseases as a maverick scientist for his next bigscreen project.

According to Variety, Ford will star in CBS Films' drama Crowley, which Tom Vaughan ("What Happens in Vegas") is in negotiations to direct.

The film is based on the true story of John and Aileen Crowley, whose two children had a rare genetic disorder. Rather than give up hope that nothing could help his children, John Crowley found a researcher (Ford) with a potential cure. Ford also will executive produce the film.

CBS is fast-tracking the project and is eyeing a start date as soon as possible.
