If you're like me...well I'm sorry, first off...than you're probably a bit impatient and look forward to the arrival of some of your favorite films on Blu-ray or DVD so you can own them and watch them 5,000 times. One of THE best things about technology is that now, thanks to digital download, we can own movies about 3 weeks faster than everyone else.
Amazon.com has Iron Man 3 available on Instant Video right now, so GO, GO, GO! It's also available via VUDU. This is the future, my friends...get used to owning things you can never touch.
