What if all movies had cell phones?

The title pretty much sets up this clip nicely, so let’s just discuss it after you’ve given it a look-see.

I personally love the Home Alone bit the most, since that could have actually been done with regular land-line phones too. Of course, there are so many other movies whose whole plots would have to change had they been set in a cell phone world, like, say, Benjamin Braddock just texting the hotel room number to Mrs. Robinson in The Graduate — which, actually, I’m a bit surprised the College Humor folks didn’t include. What other movies, PopWatchers, do you think would go through major changes if the characters just had themselves a Razr or iPhone?
