For the film, Cavara traveled to every part of the world, from Africa to Asia, Europe to Japan, putting his life continually in danger.
[1][2] Cavara eventually met up with Jacopetti again in Las Vegas, and they were both involved in the automobile accident where British starlet Belinda Lee lost her life.
[3] Cavara continued with the charming, inverted war-genre-formula drama, The Ravine with David McCallum as protagonist (a promise of '69 Venice Festival), and in 1971 Black Belly of the Tarantula, a cult thriller with a big cast, balanced between documentary scenes and an engaging performance by police inspector, Giancarlo Giannini.
A remarkable example is Plot of Fear, (his second thriller) with Michele Placido and Eli Wallach, where Cavara displayed in a new and radical shape traditional elements of gothic, police film, and Italian giallo.
Not identified as a conventional director, Cavara focused attention, over his not very long professional career, on controversial subjects and film characters, his trademark being the skillful interplay between and sensibility for visual contrasts.
