This is odd... but awesome. Apparently parts of The Avengers were shot on an iPhone. Not test shots; actual footage which has ended up in the final film and trailer. Can you spot it? It really is a case of the best camera being the one you've got on hand. Seamus McGarvey, the cinematographer on The Avengers is quoted in IFTN as saying he used an iPhone for some shots that made it into the trailer and will make it into the final film. He's quoted as saying that
The beauty of photography or cinema is that you make every choice based on the content at hand. On The Avengers, I did a couple of shots on the iPhone and they are in the movie. In fact, they are in the trailer! I understand that sometimes there is no choice and you have to go for the cheapest option, but if you are limited for choice, you can still make poignant decisions that will effect the look of the film."
Without wanting to get into a debate about the merits of any particular smartphone platform, that's amazing. As an added bonus, it allows me to post The Avengers trailer one more time. I could watch that thing all day long.
