As the new Borg vs McEnroe movie enjoyed its general release in the United Kingdom yesterday, John McEnroe delivered a typically withering critique of its inaccuracies.
The problem, McEnroe said, was that the scriptwriters had invented imaginary stories to make him look like "a jerk" - to use his own phrase - when there were plenty of real ones that would have done the job perfectly well.
"Unfortunately, even though I wished it was a good movie, I don't think it is a good movie, I'm sad to say," said McEnroe, as he came off the court after the first session of Laver Cup tennis in Prague.
"A lot of it is not accurate. I mean, I don't know why they couldn't make it accurate. They made up some stuff. There is plenty of stuff - if they wanted to make me look like a jerk at times, they could have come up with something far better than they came up with, in my humble estimation."
Since the start of the Swedish project, which stars Shia LaBeouf and Sverrir Gudnason, McEnroe has complained that the film-makers should have taken the time to involve him. He also argued they should have used the real footage of that famous Wimbledon tie-break in 1980 rather than recreating it with body doubles.
Borg was also at the Laver Cup, where he is captaining the European team while McEnroe leads the World. He was asked about the film and as usual was more polite.
"We were not involved from the beginning, me and John," said Borg. "I saw it a couple of weeks ago in Stockholm, and I thought it's OK. It's OK. But it's still a fiction movie.
"I thought what John meant, too, that it would have been more fun if we were involved from the beginning."
