Low Budget Films That Made More Than Their Money Back

Open Water – $130,000 budget

The premise of Open Water is an easy one that would help it become a box office success. It made $55 million when released in 2003. A couple becomes stranded in shark-infested waters during a scuba dive and has to survive the dangerous waters.

It received fairly good reviews and two sequels were made in the following years. Allegedly it was based on a true story, although this is unconfirmed. The production used real sharks, as opposed to CGI or mechanical props.
