'flying fox') is a 1977 action spy film directed by Po-Chih Leong, co-written by Terence Young, and starring Henry Silva, Vonetta McGee, Rik Van Nutter, and Roy Chiao.

English filmmaker Young made some contributions to the script, which led to him being advertised as a co-director in many countries, though he was not involved in the actual shooting of the film.

Despite being targeted at the American market, it was not released in the United States theatrically, and was eventually aired on CBS under the title Operation Foxbat.

Michael Saxon, an undercover U.S. spy, has secretly taken photos of the aircraft, and now he faces overwhelming odds to transport the microfilm back to his home country.

While Saxon bides time in Hong Kong, a Chinese cook accidentally swallows the microfilm, and unwittingly becomes a target as well.
