That's very cool this is the first time there was no (over)glorification of Second Life. I like that SL appeared as a matter-of-fact, as Tateru put it.
This really hasn't been done til now.

I remember watching movies from, lets say 5-8 years ago, and they had a scene where someone used the internet... and they needed to dramatically enhance the use of the web ("hackers", "the net", "johnny nmemonic") usually suddenly you'd see an orange or green glow light up the actor and the room, followed by a visual on the computer screen of laser beams and particle bits. ... just finally in movies we now see characters using google... like normal people do....

so anyway.... glad this is the first movie (a strong solid movie) to use SL as a common every day item. This is going to happen a lot more over time.
