Professional martial artist/instructor-turned-actor Jim Kelly stars in "Hot Potato". This film, released in 1975. The film is a nominal sequel to 1974's "Black Belt Jones": Here, Kelly again plays a US government agent/contractor, 'black belt' Jones, but no mention is made at all of his adventure battling Pinky & the Los Angeles Mob, so this could alternately be thought of as a prequel as well. Presumably the film was mainly meant for overseas/international audiences, as it is light on dialogue (despite the principals being American), and mostly dependent on extended fight sequences (replete with slapstick sound effects) to move the plodding plot along.
The plot-- such as it is-- involves the kidnapped adult daughter (Judith Brown) of a southern U.S. senator, who is held a fictional southeast Asian island country by a crime lord, Rangoon, (Sam Hiona). Jones is partnered with two Americans who are also martial artists, the slick-talking Chicago (Geoffrey Binney) and the potbellied Rhino (George Memmoli). A tough-talking fourth party, Thai detective (Irene Tsu), leads the rescue expedition (and guess who she falls for?) "Black Belt Jones" screenwriter Oscar Williams does double duty as writer/director here, but the film seemingly suffers. Attempts at comedy just come across as lame, as when a toy car seems to genuinely terrify a crew of indigenous henchmen, or when Rhino gets into a pick-up Sumo match with a local; A "romantic interlude" is shoehorned in just before a climactic battle, involving random fireworks, a crucified woman and a pit with two tigers.
Kelly, inexplicably paired with two bickering sidekicks, has even less dialogue here than in its predecessor. Chicago's smart-aleck front supposedly masks his pain over losing a wife and child 5 years ago; Rhino (the most obnoxious presence in the film) apparently spends his free time in eating contests with locals and trying to bed multiple women; As a "fish out of water" escapade, this film doesn't have the same impact as "Black Belt Jones" and its hip-urban-America setting. The film, shot on location in Thailand, takes advantage of the interesting visuals of the landscape, including ancient buddhist temples.
One last thing: It's a mystery just what the title 'Hot Potato' refers to, if anything: Likely just something 'clever' thought up by the filmmakers and/or the studio.
