The Last Dinosaur (Japanese: 極底探険船ポーラーボーラ, Hepburn: Kyokutei Tankensen Pōrābōra, lit. 'Polar Probe Ship: Polar Borer') is a 1977 Japanese/American tokusatsu co-production, co-directed by Alexander Grasshoff and Tsununobu Kotani (the latter billed as Tom Kotani), and co-produced by Japan's Tsuburaya Productions and Rankin/Bass Productions. The picture was filmed at Tsuburaya Studios in Tokyo and on location in the Japanese Alps. The film was intended for a U.S. theatrical release, but failed to find a distributor and ended up as a television film, airing on ABC on February 11, 1977 in an edited 92-minute run time. The film was eventually picked up for overseas markets by Cinema International Corporation, where it was released in the unedited 106-minute version as a double feature in the U.K. with the edited version of Sorcerer (the latter considered a remake of The Wages of Fear). Toho also picked up distribution rights to The Last Dinosaur in Japan for a theatrical release utilizing the unedited 106-minute version in English with Japanese subtitles, and later the film debuted on Japanese television dubbed in Japanese.

The film stars Richard Boone and Joan Van Ark. William Overgard wrote the screenplay. The score was composed, as was most of the music for all Rankin/Bass specials and series, by Maury Laws, while the title song "He's the Last Dinosaur", with lyrics by Jules Bass, was sung by Nancy Wilson, and arranged and conducted by Bernard Hoffer.
