The Castle of Cagliostro
"The Mystery of Mamo" was originally released in Japan on December 16, 1978 as "Lupin III". The film was a financial success, earning 950 million yen and making it the ninth-highest grossing Japanese film of the 1979 film season. Footage from the film, along with scenes from "The Castle of Cagliostro", was used Stern Electronics (under license from TMS) to make the "Dragon's Lair"-style laserdisc video game "Cliff Hanger". By the mid-1980s, TMS re-titled the film in Japan as "Lupin III: Lupin vs. the Clone", while English-speaking fans had begun referring to the film as "The Mystery of Mamo", to distinguish it from the two TV series and "The Castle of Cagliostro".
