Edgar G. Ulmer has a cult following because devotees claim he was able to transcend low budgets and produce films of genuine quality. However, when Ulmer wasn't involved with the material, his films were as routine as any other hack director working under similar circumstances. Such is the case with MURDER IS MY BEAT, a routine "B" thriller about a policeman who risks his job to help a girl wrongly sentenced for murder and find the real killer. The film doesn't have much visual interest, something Ulmer often injected into his films, many of which were made under shakier conditions than this. If you want to know why Ulmer has a cult following, don't see this but go see DETOUR or THE BLACK CAT.
