The film will tell the story of the 2002 clash between the Irish footballer and then manager, Mick McCarthy.
A teaser trailer for the eagerly awaited film, SAIPAN, shows Éanna Hardwicke as Roy Keane.
The film, which is set to be released later this year, tells the story of the infamous confrontation between iconic Republic of Ireland football captain Roy Keane and his national team manager Mick McCarthy during the team’s preparations for the 2002 FIFA World Cup.
A thrilling tale of football, the intense rivalry between the two personalities transcended the game, gripping an entire nation and the sporting world.

At surface level, the feud was all about standards, but deep down it was a hugely emotive story of two men whose rivalry and contempt came to surpass the sport they loved.
The film shows the definitive account of one of the most fractious fallings-out in the history of sport.
The film was directed by award-winning filmmakers Lisa Barros D’Sa and Glenn Leyburn (Good Vibrations, Ordinary Love) and based on an original script by Paul Fraser (Heartlands, A Room for Romeo Brass).
BAFTA nominated Éanna Hardwicke stars as Roy Keane, with two-time Academy Awar nominee Steve Coogan playing Mick McCarthy.
Alice Lowe, Jamie Beamish, Alex Murphy, Harriet Cains and Peter McDonald also join the star studded cast.
SAIPAN is coming soon to Irish cinemas.
