There's a terrific idea at the heart of this Irish-set thriller, particularly if you're a Catholic. A drunken Irish-American atheist stands outside a Roman Catholic Church in a small Irish village and defies God to strike him dead when out of nowhere a stranger appears and does just that in front of the local priest and the whole village. Since the killer doesn't appear to have a past or an identity, he becomes known as "Johnny Nobody", hence the film's title.

So far so good; unfortunately we get the denouement about two-thirds of the way through and it's not a very good one. From here on things get progressively more far-fetched, like a cross between a poor man's "The 39 Steps" and "Witness for the Prosecution".

Actor Nigel Patrick both directs and plays the sceptical priest, Aldo Ray is the killer and a really rather good William Bendix, the victim. Others in the cast include a miscast Yvonne Mitchell, Cyril Cusack and Niall Macginnis as well as the usual stock company of Irish players. On its level it's entertaining matinee fare but it could have been so much better.
