The Little Dragons

The Little Dragons also known as Karate Kids U.S.A. or simply Karate Kids is a 1980 American film about two young brothers who use their karate skills to rescue a friend after she is held captive for ransom. Produced and directed by Curtis Hanson. Starring Charles Lane, Ann Sothern, Chris Petersen and Pat Petersen

Although most online sources list the film as being released in July 1980, the Petersen brothers, Chris born in 1963, and Pat born in 1966 appear to be notably younger than in their various other roles during that same year. Indicated by their youthful appearance and hairstyles, the film appears to have been most likely filmed sometime between 1977 and 1978.Originally released in 1980 as The Little Dragons, the film was later released on VHS by Active Home Video in 1984 under the same title, but with the new tag line The karate kids to the rescue in order to take advantage of the popularity of the hit film The Karate Kid released that same year. The film was later rereleased on VHS by Magnum Video in 1991, this time retitled as Karate Kids U.S.A.. Subsequent DVD releases in the U.K. and the U.S. used shortened versions of both titles, retitled simply as Dragons and Karate Kids using the tag line Before the Karate Kid, there was The Karate Kids however, the most recent 2009 Music Video Distributors DVD has been released under the films original title, The Little Dragons this time with the tag line Meet the REAL Karate Kids.... ........
