These "social protest" films were also highly successful. Horror movies also enjoyed a revival of popularity in the late 60s. In the U.K., AIP struck up a film making partnership with Nat Cohen and Stuart Levy's Anglo-Amalgamated. On a trip to Italy, Arkoff met Fulvio Lucisano, an Italian screenwriter and producer who eventually headed Italian International Film, which co-produced 25 films in Italy for AIP. Due to importing completed productions from other foreign countries being cheaper and more simplistic than producing their own in-house studio films in America, AIP had released many giallo, peplum, Eurospy and Macaroni Combat war films featuring many American stars and Italian stars such as the comedy team of Franco Franchi and Ciccio Ingrassia. However, AIP released only two Spaghetti Westerns ("Massacre Time" and "God Forgives... I Don't!"), perhaps recalling their failure with Westerns in the 1950s. Many of these films were edited, rewritten with different (dubbed English) dialogue, usually by Arkoff's nephew Ted Rusoff, and sometimes re-scored by Les Baxter. AIP, through Henry G. Saperstein, is known for being the major U.S. distributor for Toho's "Godzilla" and Daiei's "Gamera" (kaiju) films of the '60s and '70s. AIP also distributed other Japanese science fiction films like "Frankenstein Conquers the World", "", "The X from Outer Space" and the South Korean production "Yongary, Monster from the Deep", as well as two Japanese animated features from Toei Animation, "Alakazam the Great" and "Jack and the Witch". AIP also released a pair of Japanese spy thrillers re-dubbed as a comedy co-written by Woody Allen called "What's Up Tiger Lily?". The studio also released edited and English-dubbed versions of several Eastern Bloc science fiction films that had the dialogue rewritten for the American market and in some cases had additional scenes filmed with American and British actors. These include the Soviet film "Planeta Bur" ("Planet of Storms") which was released by AIP in two different English-dubbed versions, as "Voyage to the Prehistoric Planet" and "Voyage to the Planet of Prehistoric Women" and the highly regarded 1963 Czech science fiction film "Ikarie XB-1", which was re-titled "Voyage to the End of the Universe".
