Starting September 25, T-Mobile Galaxy S III customers will be treated to Marvel’s The Avengers movie as a virtual preload, which they can download in the Samsung Media Hub. It’s free and a great way to show off the Galaxy S III’s awesome 4.8-inch Super AMOLED HD display.

It’s actully a bit of an odd promotion, but while reading into the details it seems like Samsung may be trying to peddle their AllShare Cast Wireless Hub: an accessory that allows Galaxy S III users to share licensed content wirelessly to any HDMI-capable TV. Either that, or T-Mobile is feeling guilty for charging its customers considerably more for the Galaxy S III than any other carrier and is now trying to make amends with free content.

Either way, it’s free and will be available starting September 25, so enjoy.
