When Farrell’s Pádraic sets out to repair the damaged relationship, Gleeson’s Colm delivers a shocking ultimatum.
The two actors previously led McDonagh’s 2008 crime-comedy movie In Bruges.
According to Variety, who was present at the recent Venice debut, McDonagh, Farrell, Gleeson, and co-star Kerry Condon were met with the “longest and loudest reception” of any film that premiered at the festival this season.
It was speculated that this might have been in response to Farrell “who broke with tradition by wading into the crowd to take selfies with fans and sign autographs, which only made the cheering grow louder and more sustained”.
Meanwhile, Olivia Wilde’s new film, Don’t Worry Darling, has received widespread press coverage for its behind-the-scenes controversies.
During the panel, director Wilde addressed rumours of a “falling out” with the film’s star, Florence Pugh.
The Banshees of Inisherin premieres in cinemas on 21 October.
