In 2013, Ross Whitaker won an IFTA for his wonderful 50-minute long documentary titled "When Ali Came To Dublin".
It chronicled Ali's Croke Park fight with Al Lewis in Croke Park in 1972, the first one after Ali was released from prison for refusing to fight in the Vietnam War.
Ali's daughter was amazed by the footage of her father when she saw the film in a Chicago screening saying (via thejournal.ie):
I’ve seen so much footage of my father over the years but the amazing thing about watching this film was that I had seen none of the footage of him in Ireland… I loved this film from the beginning to the end.
The trailer is below. Unfortunately the full documentary isn't available to buy or watch online. RTE own the film and screened it again last year, so while it isn't on the player today, it might resurface soon.
Here is the full Croke Park fight, including a commercial Ali did in Dublin at the beginning:
