The 1940s were a different time, when men called women “toots…dames…and dolls,” and women weren’t supposed to be smart, just easy on the eyes and maybe sing a little tune. The lingo and vibe of the 40s find their way easily and seamlessly into “The Big Snag,” where Pete (Eddie McClintock) and Myka (Joanne Kelly) are inadvertently sucked into an unfinished novel written by Anthony Bishop (guest star Enrico Colantoni).
