Before deciding that television was a good career move and leaving feature films, John Payne did this last one Hidden Fear for which he got a trip to Copenhagen. I've heard of worse reasons for a movie and worse films that came from them. Hidden Fear will never be ranked in his top 10 nor of the top ten of Andre DeToth the director.
Payne plays a homicide cop who's in Copenhagen because his sister Natalie Norwick's got herself in a nice jackpot with the Danish police. She's accused of murdering her boyfriend who was a dancer/musician and something of a lowlife. Payne starts running his own investigation and it turns out that the boyfriend was trying to horn in on a counterfeiting scheme that Alexander Knox and Conrad Nagel are running.
Truth be told Payne's truculent attitude probably cut a few corners, but the Danish cops probably were well on the way toward learning the truth. For that reason I can't really rate this noir film very high. In fact it could have gotten another notch in the ratings had we some color cinematography of Copenhagen and the Danish countryside.
These kind of films were disappearing and Payne probably made a right choice when he left feature films.
