HARD TIMES (formerly known as Holy Water), from director Tom Reeve and screenwriter Michael O'Mahony -- which is now available to stream via Netflix. If bearded men in nun drag turns you on (and I admit, this usually does draw a laugh or two) then this may indeed be your cup of Irish breakfast tea. And the idea of hiding your heist -- a truckload of Viagra -- in the local well from which the little village's famous holy water is drawn, also would appear to have some comic potential.
Waking Ned Devine, and the most recent of which is probably Grabbers, the rather amazing monster-movie-in-an-Irish-seaside-village, complete with a raft of funny characters. Hard Times is nowhere near the level of either film, but it manages to touch the hem of their garments, so to speak.
John Lynch (on poster, top, and above, left, as one of those "nuns"), who provides by far the most fun -- what that cast must deal with is a so-so script and direction that dawdles, at best, and really holds things up, at worst. Audiences who watch a lot of movies will find themselves way ahead of the plot twists most of the time. (The Pfizer truck supposedly loaded with Viagra plays quite a large role in the proceedings, though the credits tell us that Pfizer absolutely had no part in this film. Really? The product placement alone must have sold a ton of those little blue pills.)
Netflix streaming and perhaps elsewhere, too.
