Leif Garrett did this film a year after God's Gun (aka Diamante Lobo). In the previous film, Garrett was quite good in a challenging (for several reasons) role, but his performance felt a bit tentative (also for several reasons). In this film, just one year later and for the same infamous producers, he was confident, sure-footed and turned in a very fine performance. The film was his to carry, and he did so quite well. Garrett was one of Hollywood's most promising young actors at the time, when too many child actors were, at best, barely adequate. True, it was a low budget, cranked out film, but Leif was a class act. Lee Van Cleef had played similar roles before - many times. He could have phoned this one in, and sometimes it looked as though he did. Jim Brown, following up a legendary professional football career with a number of turns as a film actor, handled his assignment competently. The only other actors with anything significant to do were Glynnis O'Connor, who sometimes overacted and wasn't as good as in some of her later roles; John Marley, good as always in the sort of role he has played many times; and David Menachem, an Israeli child actor who did several other American films but somehow didn't catch on. He should have; he was quite good. The production values were much better than God's Gun. The script was much more coherent, the dialogue more speakable, the direction more fluid. At least part of it was shot in New Mexico (the rest in Israel). Being in the US meant that the production was controlled by a SAG contract, always an advantage. Kid Vengeance (also available at one time or another under several other titles: Vengeance, Vendetta, Take Another Hard Ride) gave Garrett the chance to launch a serious career as an actor. He demonstrated that he was up to the challenge. But then the music producers came along. Too bad.
