Two movies with almost the same name and plot are released together.
Overlord (2018) was released on 9 November 2018 in the USA and produced by J.J. Abrams who is a well-known director and producer in Hollywood. A second movie is Nazi Overlord (2018), released on 13 November 2018 in the USA and produced by not so well known people.
From the synopsis, both movies have almost the same plot and name.
This related question is about twin films whereas I am asking about low production studios making intentional releases shortly after the release by a big banner.
What's the point of releasing such similar movies at the same time?
