Edmond O'Brien became the latest actor to try his hand at directing in MAN-TRAP (he'd previous functioned as codirector on 1957's SHIELD FOR MURDER). Jeffrey Hunter stars as an impressionable fellow whose old marine buddy (David Janssen) talks him into a questionable business venture. Hunter joins Janssen in a plot to hijack nearly four million dollars from the Mob. The results are far from beneficial, either for Hunter or his alcoholic, promiscuous young wife (Stella Stevens). MAN-TRAP was adapted from John D. MacDonald's novel TAINT OF THE TIGER.
