Updated: It turns out that Seamus McGarvey was misquoted. From The Hollywood Reporter:
"I was talking about how up and coming film makers have access to a whole range of new technologies which expand our options as filmmakers. I mentioned that the iPhone and the Canon 5d Mk2 were devices currently used on many Hollywood productions. I used the Canon on some shots on Marvel's The Avengers movie," he stated to THR. "Unfortunately, this was edited to read that I shot some of the film with the iPhone. This is not true."
The original story follows:
The iPhone 4 has a great camera built-in -- but it is good enough to film a movie? According to cinematographer Seamus McGarvey, who worked on the upcoming Avengers movie, the iPhone works just fine as a cinematic instrument. In an interview with the Irish Film & Television Network:
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.
McGarvey gave no details about exactly which shots in the trailer were taken with an iPhone. It's a testament to the iPhone and McGarvey's abilities as a cinematographer that we can't figure it out.
