Following Watching and Waiting (2008) and The Ballad of Des & Mo (2010), this will be the third feature film from the team behind The 72 Project (a series of films shot and edited in 72 hours).
The enlarged photo on the "Barred" pub poster is that of "Dennis the Bar Punter" - played by Blogger/John Shelton (VIII).
The Kevin and Barry storyline (played by Rory Mullen and Ewen MacIntosh) was reworked from 'Keys To The City (2012)' (also co-written by James Fair). The characters were called Eoin and Barry in Keys to the City, and Rory's real life brother, Conor Mullen, played Eoin's character.
The very first screening of The Confusion of Tongues, was at The Giant Screen Cinema in July 2014.
One storyline in The Confusion of Tongues had originally been written for Keys to the City (2012), but the genre was rewritten from farce to drama. Conor Mullen, played Eoin Mooney (a surviving pun on 'owing money') in Keys To The City, his brother Rory Mullen played the equivalent character Kelvin in The Confusion of Tongues.
