Overture Films and Echo Lake Productions are set to produce 105 Degrees and Rising.
The film is set against the backdrop of the fall of Saigon in 1975; Jon Amiel is attached to direct from a script by William M. Akers. The story weaves together several arcs as the characters struggle to escape South Vietnam during the final days of the U.S. control over the former capital city, culminating with the dramatic evacuation of the last Americans and many South Vietnamese via helicopter from the roof of the American embassy.
The Hollywood Reporter notes 105 Degrees and Rising's title is based on a secret code broadcast on Armed Forces Radio. The announcement that "the temperature is 105 degrees and rising," followed by eight bars of Bing Crosby's "White Christmas," meant all U.S. citizens should immediately evacuate Saigon.
