The Wild Wild World of Jayne Mansfield

Under the working title "Jayne Mansfield Reports Europe", actual footage of her in Paris and Rome was shot in the spring and summer of 1964, and edited with clips from other movies. On her return to America, additional filming in New York City and Hollywood was done later the same year. All segments were done in Mondo style. Following Mansfield's death in 1967 accident, portions of her narration for this film were recorded by an uncredited voice actress who sounds like her.

The featured persons in the opening credits ends with «...and a cast of thousands of Jayne's friends all over the world». This is blatantly not true, as if the number of pedestrians do not reach one thousand if you count them all, and Jayne is shown in very few parts of the world. A crazy hype for the movie.

In Italy, after the initial ban (July 30, 1968) the Distributor Patry Film got an approval for adults (over 18) but to copy cut to 2100 meters (76m33s).
