The new outer space thriller Gravity has soared to a stellar opening weekend.
The film took in $55 million just in North America.
It was also the best ever debut for its stars, Sandra Bullock and George Clooney.
That says a lot, but what do real astronauts think about it?
Jeanne Moos talks to someone who truly appreciates Gravity's relentless pull.
Who better to review the movie Gravity than a guy who doesn't just talk the talk, but has actually walked the space walk?
What you see in the movie is kind of like a bad day -- not just a bad day, but a bad day on steroids.
On his two flights into space, Mike Massimino never had debris crash into him as Sandra Bullock does.
Instead of being flung into space...
I can't breathe.
...Mike's space walks were like a slow dance, not a body slam.
But when it comes to realism...
I was really excited when I saw the accuracy of my telescope and payload bay and tools.
I was like, this... I wasn't looking at Sandra Bullock at all, sorry. I recognized my wire cutter.
...what Mike did not recognize was Sandra's heavy breathing.
You're burning oxygen.
Stop panting.
That's not helpful. No, that is not helpful. When you're breathing heavy, you're using more oxygen.
Maybe it freaks you out to see Sandra untethered, floating off into blackness.
Anybody, please copy.
Yeah, I didn't like that idea, neither [either].
Astrophysicist Neil deGrasse Tyson nitpicked via Twitter,
noting that nearly all satellites orbit earth west to east, not east to west as in the film.
And he pondered why Bullock's hair, in otherwise convincing zero-gravity scenes,
did not float freely on her head, as even Mike's short hair did.
It kind of poofs a little bit.
The real astronaut doesn't quibble with Sandra Bullock's spacesuit.
It's what's under her space suit that wasn't so realistic.
The undergarments were not accurate, but again, it's a movie.
And which would you rather see,
Sandra Bullock in boy shorts or the fancy long underwear with tubing that real astronauts wear under their space suits?
While the movie astronauts were having their tethers severed, the worst thing that happened to Mike was a hole in his glove.
So then you started going... (panting).
No, no, no. No panting.
Mike says he misses being up in space, and the movie reminded him of being there.
For me, yeah, I'm just an astronaut. I'm not a movie critic, but I give it a thumbs-up.
Just an astronaut. An astronaut more worried about holes in his glove than holes in the plot.
