During World War II, the Women Airforce Service Pilots (WASP) asked permission to use the image as their official mascot, and the Disney Company granted them the rights.
[N 1] With Dahl's assistance, a series of gremlin characters was developed, and although pre-production began, the film project was eventually abandoned, in part because the studio could not establish the precise rights of the "gremlin" story, and in part because the British Air Ministry, which was heavily involved in the production because Dahl was on leave from his wartime Washington posting, insisted on final approval of script and production.
[4][N 2] The publication of The Gremlins by Random House consisted of a 50,000 run for the U.S. market[N 3] with Dahl ordering 50 copies for himself as promotional material, handing them out to everyone he knew, including Lord Halifax and First Lady Eleanor Roosevelt, who read the book to her grandchildren.
[6] Reviewed in major publications, Dahl was considered a writer-of-note and his appearances in Hollywood to follow up with the film project were met with notices in Hedda Hopper's columns.
[7][N 4] Facing copyright problems and realizing that the Air Ministry's "Clause 12" in the original film contract would restrict the studio, Walt Disney, who had a personal interest in The Gremlins, reluctantly began to "wind down" the project.
