Oscar-winning director Steve McQueen said he was "honored" to collaborate with two leading actors, Liam Neeson and Colin Farrell, in the upcoming Vdov thriller.
The film tells the story of a group of women robbing robbery after their killers killed in a police shootout.
Neeson plays one of the husbands (his wife Veronica Rawlins plays Viola Davis) while Farrell plays Irish-American politician Jack Mulligan.
"Liam and Colin, they are amazing actors and they have been doing amazing work in Hollywood for a long time," said McQueen, who also directed 12-year-old Slave.
"I was honored to work with them, especially in Chicago, where there is such a kind of Irish foundation."
McQueen was particularly impressed by Farrell, who improvised many scenes with his father on screen, Robert Duvall.
"Robert Duvall and Colin were so amazing they worked together, like two musicians who were just getting stuck," said RTE Entertainment.
"A lot of the things to do with the screen are improvised."
Widows to be released late this month have received almost universal positive praise from critics, and currently have 96 percent rating for Rotten Tomatoes.
The film McQueen wrote with Gillian Flynn, Gone Girl, also stars Michelle Rodriguez, Daniel Kaluuya and Elizabeth Debicki.
Meanwhile, a new trailer was released for the next Neeson's upcoming films.
Ballymena will play alongside Brendan Gleason, Tom Waits, and James Franco in the new six-part anthology The Ballad Of Buster Scruggs.
Every "chapter" of the film tells another story about the American West.
He has already won the Best Screenplay at the Venice Film Festival.
