Practicing A More Complex Shot

I wanted a shot where the actor holds the camera towards himself to parody 127 hours. I thought this would be funny because the students have only been stuck for about an hour but they are making a really dramatic situation out of it. Once I had filmed it, I thought that it would be good to make the screen look as if it was shot using a phone which is what the character would be using to film himself in this situation. This was also harder to edit because iMovie doesn't have a setting to make the screen look narrow.
