I actually did see the clip, after I made my post. I realize the spin is that it was a real stunt, but I'm going to argue that this is more of a publicity stunt than a real stunt.
Well, I don't doubt that it's a real stunt, not a publicity stunt.
As in, zero doubt.
I won't go into it, but he's a KNOWN commodity for doing this. Like I said. The first I'd heard of it was from the financial side re: MI. My dad used to work in banking and used to know people on that side of the table (specifically the concert and film underwriting folks) and trust me when I say that the people quoted in that Variety article, I think it was, were completely freaked out. So much so that Cruise had significant issues getting his next movie financed even though MI was a huge success. Both MI and Jerry Maguire were released in 1996 and he didn't have another release until 1999 and neither were action movies. MI2 was released in 2000, but rest assured, immediately upon release, they were working on the details to get into production and they hit roadblocks. There was significant doubt if MI2 was going to be made at all because of that helicopter stunt (I said earlier it was the eye, it actually was the helicopter blade to his neck... in MI2, he upped the ante and had Dougray Scott hold an extremely sharp knife a measured 1/4th of an inch from his eye. Even though it was tied to a cable, the slightest slippage and that knife is half buried in his skull).
Again, in MI2, while he didn't free climb, he had cables, those aren't fool proof.
So, let's just say that while I only know a small bit, what I know is that financing a Tom Cruise movie is an underwriting NIGHTMARE because he really does do this stuff.
If he didn't, they wouldn't have trouble underwriting a movie that easily grosses $100M more than the studio took to make it...although to be fair, no movie ever has made a profit. Just ask the studios. I'm pretty sure not even Avatar made a dime...
I mean feel free to believe whatever you want to believe. I just know within more than a margin of error that he did it.
