This production was originally made for tv but received a spotty theatrical release in some places. The dialogue is all in Gaelic, which gives Hero a certain obscure novelty value. But it almost approaches the unwatchably bad in its sheer amateurism. The cast were people with no prior acting experience who were dragged in off the streets and gotten to perform their lines in rote fashion – and appreciably most of them give the impression of being obviously bored and with no idea what it is they are saying. The results look exactly like what one would expect to get if they hired a group of extras, gave them army blankets and fake swords and let them run around in the mud. This is a problem surely not only helped by having a script written in Gaelic but with its dialogue all subtitled in dreadfully pretentious epigrams. What passes for a score is incredibly bad.

The film was shot in Argyll, Scotland which is one of the dreariest landscapes imaginable. Which is all a shame as the film actually does develop a plot of sorts in its latter half and given the proper opportunity the legend of Finn Mac Cool is one that looks halfway filmable.
