Lights Out (2013)
In 2013 David F. Sandberg and his wife, Lotta Losten, released this 3 minute short they made together on the internet. 3 years later the full length film was released in the United States and made 10 times its budget in 2 weeks!
If you have seen the trailer for the movie or seen the movie then you have an idea what this short is about. There is no dialogue and it is VERY short, but it is effective and very scary, which is why they decided to make a full length film of this.
Obviously there is not much to say about this version of Lights Out, other than I would watch this after you see the full length version. I am happy to see that he used his wife in a role in the full length as well, it's nice that he could work that out.
