There are plenty of choices for streaming services out there. Between Netflix, Hulu, Amazon Prime Video, and others, you are probably paying a good amount of money for all these. However, there are plenty of free services--like Crackle--that offer up new content every single month. Here is what is coming to Crackle this April.

While Crackle is free, it is ad-supported, meaning as the content you select plays, you're going to get some ads. There are 30-second and 90-second ad breaks scattered throughout the movies and TV shows, but it's a free service. Additionally, there is original and exclusive content on the service as well.

The coolest exclusive for the upcoming month is the documentary Memory: The Origins of Alien. The film takes an in-depth look at the film that redefined science fiction. This includes adapting the artwork of H.R. Giger and director Ridley Scott's vision for the film. Check out the trailer for the film below.
