Redbox Instant is one of the newest movie streaming companies on the block and needs to add customers. This need likely led to a promotion in which users had to tweet to unlock a free movie rental. The movie in question? The Hobbit. So, did they succeed? They did and you can now rent The Hobbit for free.
To receive the free rental, you'll need a free Redbox Instant account and you'll need to rent the movie before 12a.m. ET on May 23. This means you'll need to complete the rental in the next 9 hours or so. After you rent the movie, you'll have up to 30 days to watch it. However, "Once you start watching it, you have 48 hours to view the movie as many times and on as many supported registered devices as you choose."
Redbox says they'll run future promotions of this same nature, though we don't currently know when the next one will take place.
