The Scot's post-match press conference following his wind-assisted 5-7, 6-2, 6-1, 7-6 (9-7) victory over Tomas Berdych was gatecrashed by Sir Alex Ferguson and Sir Sean Connery.
The two knights of the realm are in town long enough to stay for Monday's final against Novak Djokovic, who beat David Ferrer today after a weather delay, and the 25-year-old Murray thanked both men for their support.
"It's great," the Scot said. "You know, that's the first time I've met Sir Alex and the first time I met Sir Sean, as well. So it's obviously nice to have their support. Hopefully they'll be back for the final, as well."
The Manchester United boss is a big fan of Murray's and also attended this year's Wimbledon final. He excused himself club duties for a few days due to the international football weekend break.
"I've been coming here the last three years to New York, and I have been explaining how Scotland invented the world," said Ferguson, during his impromptu guest spot. "Well, today we invented the wind."
Ferguson was referring to the mighty gusts attached to an encroaching tornado in the New York area which caused havoc during the Murray match.
The Scot's hat blew off in the middle of one point, his chair and bag were sent flying as he prepared to serve for the second set, and play was frequently interrupted by all manner of debris getting blown across the court.
The Olympic champion adjusted to the conditions far better than his opponent, but said it was as difficult match circumstances as he had ever encountered, even when practising amid the challenging conditions he sometimes experienced as a youngster in Scotlad.
"I did practise in tough conditions, because obviously it can get incredibly windy," the Scot said. "But nothing like it was today, that's for sure. It's probably the toughest I have played in.
"I played Rafa in the final of Indian Wells once, and that was also not much fun. I played in Vegas once as well when it was really, really windy, but not for such a long period.
"You know, it was pretty much four hours, the match, and it was brutal. There were a few games in the fourth set where it calmed down a little bit, but they were very, very tough conditions to play in."
The tournament will now extend into Monday for the fifth successive year but the Scot was unsure how much of an advantage it would be to have an extra day's rest on his opponent.
"You know, I have been in the position before when I played in the final [in 2008] where...I didn't get the day off and maybe it hurt me a little bit," he said.
"But Novak and David are very, very experienced, so I'm sure they will deal with the situation better than I did back then anyway. But it will be nice to get a rest on Sunday and practise and get your rhythm back."
A disappointed Tomas Berdych claimed the match should not have gone ahead. The Czech player felt the conditions altered the nature of the match completely, and called for rules to be brought in to make strong wind as unplayable as rain.
"I think our sport deserves to have some rule if the conditions are like that, like the one that you don't play because of the rain," the 27-year-old said.
"We play in a Grand Slam, in such a big tournament like this one, and especially missing the roof, it's something which we should at least think about.
"This wasn't about putting on a show. This was just about ... trying to put ball over the net. Sometimes it was impossible. But that's how it is. Nobody cares."
Murray knows better than most how difficult it is even to get within touching distance of winning a grand slam, and he is hoping experience can carry him over the finish line when he contests his fifth final tomorrow.
Only Fred Stolle in the 1960s has ever lost his first five grand slam finals, and Murray is hoping to emulate his coach Ivan Lendl, who also lost his first four before breaking his duck at the French Open in 1984.
Murray is certainly getting closer. In his first Wimbledon final in July, the 25-year-old won his first set in a final and pushed Roger Federer all the way before finally succumbing in a flood of tears.
But three weeks later he was back on Centre Court and turning the tables in spectacular fashion, with not just victory over Federer but a rout to win Olympic gold.
Murray said: "I think all experiences like that help. In some ways maybe it took a bit of pressure off me, but I do think that even having played here and lost in the final, that is also a good experience to have gone through.
"Having to deal with all these different weather conditions and matches getting suspended. Obviously now I have a day off. Mentally you're preparing to play Saturday and Sunday.
"I've had quite a lot of breaks during this tournament as well, so it has been hard to stay in a rhythm a little bit. All of those big matches and all of the slams and Olympics and stuff, they all help in the long run."
Murray's previous run to the final at Flushing Meadows came four years ago when, in his first experience of a grand slam showpiece, he was beaten in straight sets by Federer.
Seventeen months later he made the final at the Australian Open, again losing to Federer, while the following year in Melbourne he was comprehensively outplayed by Djokovic at the start of the Serb's phenomenal season.
Over the last two seasons, Murray has made three grand slam finals, four semi-finals and one quarter-final, and he said: "My results in the slams over the last couple of years have been very good.
"And obviously this year, in the major tournaments, along with the Olympics, it's been my best year. I'd never made two grand slam finals in a year, so that's obviously a good sign that I'm playing better and still learning.
"And the Olympics was the biggest win of my career by far. It meant a lot to me, too. Whatever happens in the final, it's been a great year. But all I want to make sure I do in the final is give 110%. I know how hard these opportunities are to come by and I will give it everything."
Murray is, of course, looking to end one of the longest droughts in British sport and become the first man since Fred Perry 76 years ago to win a grand slam singles title.
The last of Perry's titles came in America when he beat Don Budge in five sets, while, were Murray to win tomorrow, it would mark exactly 79 years since the Stockport great won the first of his major trophies at the US Open.
Murray added: "It's the last thing that I really want to achieve in my career, so that's why it's obviously very important for me. Winning the Olympics did, for me, take a bit of the pressure off. I did feel a lot better after that. I maybe had less doubts about myself and my place in the game just now.
"But winning a major is the last thing that I really want to do. It means a lot to me. You saw at Wimbledon how much that meant to me. It's obviously not easy to lose another slam final, so I hope this one is a different story."
