Steve Coogan will play Mick McCarthy in a new film portraying the events of the Republic of Ireland manager's bust-up with captain Roy Keane ahead of the 2002 World Cup.
Keane ended up leaving the Ireland camp before the start of the tournament in Japan and South Korea after a public falling out with McCarthy.
The pair were involved in a verbal altercation after Keane had given an interview to a newspaper bemoaning the preparation and facilities laid on by the Football Association of Ireland.
Keane had already been convinced to reconsider a decision to quit the squad only for the falling out to lead to the Manchester United midfielder leaving anyway.
'Saipan' - the Japanese island were Ireland were based - will tell the story of events leading up to Keane's departure, with Alan Partridge star Coogan confirmed in the role of McCarthy.
Meanwhile, Keane's role will be played by 27-year-old Irish actor Eanna Hardwicke (above)
Keane will be played by Eanna Hardwicke with production due to start soon with a slated release date of next summer.
'A million words have been written about what happened on that fateful week in 2002 on the tiny island of Saipan,' said producers Macdara Kelleher and John Keville.
'Next year audiences will finally get to experience first hand the feud between Roy Keane and Mick McCarthy and why it was labelled 'the worst preparation for a World Cup campaign ever'.'
Without Keane, Ireland finished second after going unbeaten in Group E, including a last-gasp draw against Germany, before losing on penalties to Spain in the round of 16.
McCarthy resigned in November 2002 and Keane returned to the Ireland fold under his successor Brian Kerr but retired from international football after failure to help the nation qualify for the 2006 World Cup.
