Speaking of making movies with your cell phone:

'The Commuter' staring Dev Patel, Pamela Anderson, Charles Dance, Ed Westwick and shot entirely in mobile HD on the Nokia N8 smartphone.

i saw a samsung taking photos and film clips better than any DSLR or any Camcorder i've ever seen, with some new night shot feature that made the photo look really great, clear, fast shutter, sharp image, all at night.. this guy made better pics with his phone than a whole line of SLR users

i think it was samsung.. some phone from korea, he was a tourist from Korea.. i couldnt believe it
