Apple started sending out free iTunes movie rental codes to iTunes users today. The promo code will allow you to rent one of the 8,500 available movies.

Redeem your free movie rental below, and start watching one of your favorite movies on iTunes. Watch what you want, when you want. Enjoy movie rentals on your iPad, iPhone, and iPod touch, the all-new Apple TV, or on your computer. You have 30 days from the moment you rent a movie to start watching, and 24 hours to finish it.

Apple has not indicated the reason behind this promotion, but we're not complaining - we'll gladly accept a free rental. Perhaps this is Apple's way of saying "Happy Holidays".

Who's received a free rental code? What do you plan to rent? Do you plan to watch it on your iPhone or iPad?
