This brilliant story appeared in the Irish Press in December 1972. It has everything. A visiting film crew decided to pack a job in owing to numerous incidents in Dublin, ranging from local youths flinging stones to the locals calling the Gardaí terrified, and some of the cast were even reported to have been ‘acting suspiciously’by worried locals!
In addition to all this, a huge number of prop guns were seized from the production team at Dublin Airport upon arrival! What became of Mother Mafia’s Loving Fold? I’m unable to find any reference to the film online. John Murphy, producer of the film, described it in newspapers at the time as a send up of The Godfather and Hollywood gangster films of the 1930s.

Dubliners are very resilient.

It looks like this film eventually surfaced as “Tutti Figli di Mammasantissima”. The director is the same on mentioned in contemporary Irish news reports (Alfio Caltabiano) and there are a couple of Irish actors. There are a few screen shots on the Internet Movie Cars Database, some of which look very much like the North Wall area, plus there is confirmation from movie credits that part of the film was shot in Ireland.
