A director who brought Nottingham Forest's European Cup winning side to the silver screen has said he would give Wales the same treatment if they won Euro 2016.
Jonny Owen, a Cardiff City fan from Merthyr Tydfil, was behind I Believe In Miracles about Brian Clough's glory years in charge of the Reds.
The film - which was lauded as "the greatest football film ever made" - charted the meteoric rise of the Reds from mid-table Second Division side to European champions in 1979 and 1980.
Mr Owen, who starred in Shameless and wrote and produced Svengali, is in Lyon for Wales' semi-final clash against Portugal on Wednesday.
He said: "This team has been one of the great Welsh teams in the history of Welsh sport... they will go down forever more as one of our greatest ever teams."
Speaking about the idea of a documentary on the Wales team, he said:
If we won, absolutely. Because it would probably be one of the greatest stories in the history of team sport if Wales won the Euros.
Wales are 90 minutes away from securing a place in the final in Paris on Sunday after knocking out Northern Ireland and Belgium in the last two rounds.
The side last qualified for a major tournament in 1958 - eventually getting knocked out of the World Cup by Brazil 1-0 in the quarter-finals.
