Since I don't really follow Hollywood I found out about this movie only yesterday. I haven't seen it yet, but watched the trailer. So apparently there's something about this movie that provokes poking holes in its portrayal of physics -- I immediately got very annoyed while watching the trailer. First, they don't have their visors (those Sun protective, gold plated ones). I'm not sure, but I guess that's a big no-no on EVAs, having the Sun enter your field of vision so close to it (in Earth's orbit) would probably do some eye damage. Again, I'm not sure the visor is always mandatory but I don't remember seeing any photos of actual EVAs without it being down. Second, Sandra Bullock rotating while attached to Canadarm... My impression was that the g force would be too high for her to stay conscious, or able to communicate. But it turns out intuition was wrong on that one: back of envelope calculation gives ~3 g (assuming 15 m length for the Canadarm [assuming it is the Shuttle Canadarm], but it was slightly retracted so it would be less, and a period of ~4 s) while still attached to the Shuttle, and ~1.5 g when the arm broke off (~3 m radius, 2-3 s period). So, that's OK. :) Third, the abuse those suits were getting! That's just crazy. At that point I got so annoyed that I didn't bother to notice all the other stuff the article talks about. Now I'm just bummed out that all this might have spoiled the movie for me (I tried not to read the plot section on Wikipedia, but got a glimpse of the ending as I was scrolling). Nerd rage is a horrible thing. :)
