Blu-Sky Media has acquired feature rights to Erica Jong’s 1973 comic novel “Fear of Flying” from Sony Pictures for producers Donald Kushner, Leigh Ann Burton and Piers Ashworth.

Project had been set up with John Calley’s production company, with Diane English scripting. Ashworth is penning the new adaptation, which will be updated to the present day.

Jong’s novel was a sensation when first published for capturing changing attitudes toward sexuality and has sold over 26 million copies. “Flying” is narrated by protagonist Isadora Wing, who is in a failing second marriage and embarks on an existential sexual odyssey across Europe.

Jong is co-producing the film and called Ashworth’s screenplay the best adaptation of her work. “It is brilliant, witty, boisterous and fun,” she said.

Jong also wrote two sequels, “How to Save Your Own Life” and “Parachutes and Kisses.”

Producers plan for the start of production to coincide with the international re-release of the novel’s 40th anniversary edition in late 2013.

Kushner’s credits include “Tron Legacy” and “Monster.”
