Oh there was air in the background, but no direct support. How would they have communicated?
I thought it was a great film. People have asked me if I enjoyed, and I can't say I enjoyed because it's just too gritty to be enjoyed, but I did think it was a really good film. I found it quite tense at times and found myself thinking "c'mon! c'mon! faster! faster!"
I did wonder if f**kstick had been invented back then tho....
