“Gravity” is the most realistic space movie ever. I mean, that Clooney guy looks just like me!

Actually I’ve been besieged with questions about what I thought about this movie ever since it came out. Just here at work at SpaceX last week, I was asked that question about a dozen times a day. I quipped that “What do you think of “Gravity”?” was becoming every astronaut’s least favorite question, surpassing even “How do you poop in space?”

So, to help me deal with this onslaught, here is my more serious attempt at a movie review:

First of all, it’s a great movie. The pace and story was definitely engaging and I think it was the best use of the 3-D IMAX medium to date. Rather than using the medium as a gimmick, “Gravity” uses it to depict a real environment that is completely alien to most people.

But the question that most people want me to answer is, how realistic was it? The very fact that the question is being asked so earnestly is a testament to the verisimilitude of the movie. When a bad science fiction movie comes out, no one bothers to ask me if it reminded me of the real thing.

The movie does an outstanding job of capturing what it is like to do a spacewalk – much better than any previous sci fi film. Having done three spacewalks myself, I can tell you – this is legit. The visual impact of having nothing but the glass of your helmet between you and the Earth is captured very well. (Although the Earth is a bit more sharp and vivid in the movie than the real thing. Plus there is almost always an interesting land-mass to look at when in reality you spend most of your time looking down at a less-interesting ocean view.)  Also, the movement and physicality of doing a spacewalk is rendered in a very accurate manner. The ease of starting a motion and the difficulty of stopping it in the vacuum of space is captured accurately in many scenes.

It’s amazing how many things “Gravity” gets right. When Sandra Bullock’s character turns the two valves to shut off oxygen flow to the Soyuz – those are exactly the correct valves to turn. When she wants to command the orbital maneuvering engine, the CKD, she pushes the correct button which is also labeled correctly. The interiors of the Soyuz and the International Space Station, are pretty realistic although the various modules are not the correct position.

And the danger of space debris is very real. During my first spacewalk, my partner, Rick, had to bring in a handle that was stowed on the outside of the station. When he got it inside he noticed a hole, about a millimeter in diameter, that was shot through the half-inch solid aluminum material by a piece of orbital debris. It looked like someone had taken a cocktail straw and shoved it right through the metal. He looked at me and said, “If that hit one of us…” There was no need to finish that sentence, since such an event would have been instantly fatal, although I pointed out that he is about 6′ 2″ tall and I am about 5’5″ so it was much more likely to hit him instead of me.

Ironically, the fact that the movie got so many things correct made it very disconcerting for me when the movie did get several things completely wrong.

SPOILER ALERT!! Stop reading now if you do not want key plot points revealed.

Yes, there are major violations of the laws of physics and minor violations of typical astronaut behavior in the movie. The biggest error is that there is no way to go hopping from one spacecraft or space station to another so easily. It takes tremendous energy and careful planning to change orbits. For example, as was made so clear in the aftermath of the Space Shuttle Columbia tragedy, even with it’s flight computer, a full tank of propellant and hundreds of people on the ground to support, there was no way for the crew Columbia to reach the safety of the International Space Station. You can’t just look around and see another spacecraft and then get there by simply pointing in the general direction with some soft landing jets and a fire extinguisher.

Another huge error was – there was absolutely no reason for Clooney to sacrifice himself!!! Once Sandra caught him, he would be just floating there. A small tug on his tether would send him back to the space station. And as my wife put it, when you have a hold of George Clooney, only an idiot would let him go.

Of course, at the speed he was tumbling by her, there is no way she would have caught him in the first place. He weighs a few hundred pounds and his suit weighs a few hundred more. Try lying on a sheet of ice while a 500 pound weight goes flying by and then try to grab a tether attached to that weight while wearing a pair of gloves from a medieval suit of armor. Not so easy.

Also, how was Clooney going to beat Anatoly’s space walk record if astronauts apparently don’t wear either a diaper or a cooling garment under their spacesuits? That would be one smelly suit. Although I have to admit, that Sandra Bullock looked much sexier in her tank-top and boy shorts than I did when I took off my spacesuit:

Yes, I could go on and on about all the things “Gravity” got wrong. If you put me in a Chinese spaceship, there is no way I would be able to figure out how to fly it home. An astronaut that took joyrides around the Hubble Telescope with a jet pack shouldn’t even bother coming home. And a debris field in low earth orbit would never take out geostationary communication satellites.

But who cares?

All of these inaccuracies were done to help advance the plot or to add drama to the film which is exactly the artistic license we should be willing to grant the filmmakers. This is entertainment, not a documentary.

Recently, I was at an event where Neil Armstrong’s son talked about his father’s many wonderful qualities and one bad one – it was very difficult to watch a sci fi movie with his dad. He would complain if one instrument was out of place on an aircraft’s panel. He objected to the catapulting of fighters off the Battlestar Galactica – it’s not like they have to build up airspeed to get aloft – why not just plop them out the door?

With all due respect to one of humanity’s greatest individuals, I don’t want to be like that.

It’s just a movie – and a very good one.

几段：
“引力”是我看过的最真实的讲述太空的电影，我是说，乔治克鲁尼跟我简直太像了

电影出了之后，人们最想问我的问题就是“这片子假不假”. 其实大家这么热烈的问这个问题正是这个片子最好的写照，要这是个烂片，根本没人理我

“你觉得引力这电影怎么样” 已经超过了 "你在太空怎么大便“，成为了所有宇航员最不喜欢的问题

确实，我可以一直唠叨这电影的所有”硬伤“，如果把我放在天宫一号里，我肯定飞不回去。一个在哈勃望远镜边上无所事事飞来飞去的宇航员还是别回来的好，在近地轨道的碎片也干不掉静止通信卫星。
但是， WHO CARES？
所有这些为了帮助推进剧情的”硬伤“是导演为了艺术表达应有的执照。这是电影，不是纪录片。
我在最近的一个活动上听了Neil Armstrong的儿子讲述他父亲的众多优秀品质和很一个很差劲的地方： 他根本没法和他爸爸一起看科幻片。他爸爸会一直抱怨如果一个飞机上的仪器放错了地方。他反对太空堡垒的弹射装置，”他们又不是非要空速才能飞？干嘛不把他们直接扔出去。“
我对这位人类先驱充满了敬意，但我不想成为这样。

这只是一个电影而已，一个好电影。

引人入胜的故事与（紧凑的）节奏,而且我认为这是目前运用3-D IMAX 最好的电影.
