James Cameron’s first movie since Titanic in 1997,Avatar,was previewed at Comic Con yesterday. And according to most people there to watch it,it was awesome. And we get to see it,in about a month. The plan is that come August 21st,Fox is going to get a hold of as many IMAX and 3D screens it can around the world to provide people with a 15 minute free preview to Avatar. I am excited to this in a theater near me soon. Hopefully someone leaks it to YouTube before that,I hate waiting…
