It could be a hoax, someone who shot that footage and added it to the DVD extras as a joke.
But assuming that the footage is real, I'm sure there are explanations for it. What Nestor and Murphy say is quite possible. Keep in mind that our brain is 'wired' to recognize patterns and form associations which is why we instantly think of a cellphone when we see somebody walking on the street with their hand next to their ear. But that doesn't mean that it
is a cellphone.
Time travel fascinates me, it's a very interesting subject IMO. Who knows, maybe one day it will be possible.
It could be used for a lot of good, but a lot of bad as well...
Do you guys remember John Titor? It's a true internet classic. I've forgotten about him but now that time travel is brought up I'm reminded of him. Way back in 2000 someone on a forum claimed that he was a military time traveler from the future. Now of course anybody can say he's a time traveler on the internet, but John Titor's story was different in that he explained things in a very detailed manner, and seemed to be very scientifically literate. He even showed pictures of his 'time machine'. Keep in mind, this was in 2000 when the internet wasn't as popular as it is today and trolling wasn't as apparent yet I guess. He probably was just a troll, but a very intelligent one at that
Check it out, even though it may not be true it's fascinating.

The second link contains an archive of all of his posts etc. Great stuff. Now I gotta read all of that again.
