Tunnels aka Criminal Act. (1989) – Mark Myers.

While I cannot readily recall any specific box office bonanza set in a city sewer, there are a number of genre gems like C.H.U.D, Alligator, and schlock scion The Suckling aka Sewer Baby that provided some credible subterranean shocks! Not quite so lurid, playing out like an episode of The Equalizer, Tunnels finds our intrepid, conspicuously attractive heroines Pam (Barbara Bach) and Sharon (Charlene Dallas) investigate a suspicious death, that ultimately leads them to the shocking truth lurking malevolently below! Competent, though not enormously thrilling, Tunnels remains a passable 80s curiosity that has a capable supporting cast, bolstering our two saftig, especially picture perfect leading ladies.

While there are far greater numbers of obscure genre/B-titles being made available today, I'm not always convinced by their continued merit. Tunnels is worth reinvestigating, having an above average TV-Movie-of-The-week aesthetic, plus a disarming duo of pretty, wonderfully engaging female protagonists. John Saxon is always a joy, and Vic Tayback provides a brief, somewhat tangential comedic interlude. The only giant rats are the CEO's running amok in the sewers of big business, embodied by cynical property developer Lance Bellard (Victor Brant). The climax is glaringly goofy, but it didn't discolour my overall appreciation of this fun little B-thriller.
