You can rent Super 8 today for just $.99. Here is a little about the movie:
In the summer of 1979, a group of friends in a small Ohio town witness a catastrophic train crash while making a super 8 movie and soon suspect that it was not an accident. Shortly after, unusual disappearances and inexplicable events begin to take place in town, and the local Deputy tries to uncover the truth – something more terrifying than any of them could have imagined.
The nice thing about this is that you have 30 days to actually start playing the movie- so it will sit in your Amazon account until you are ready. Once you push play you have 24 hours to watch it and then it goes away.
