Black Rock is a 2012 American horror-thriller film directed by Katie Aselton, with a screenplay by her husband Mark Duplass.

Black Rock stars Aselton, Lake Bell, and Kate Bosworth as three friends who reunite after years apart on a remote island but end up having to fight for their lives.

[3] Sarah invites her childhood friends, Louise and Abby to a remote island that they once spent time at in their youth, in hopes of bringing their distant group back together.

As they crawl towards the shore, Sarah loudly protests the plan and runs back towards the tree line where she is shot in the head by the men.

They then find the time capsule and retrieve a Swiss army knife from inside which they use to sharpen sticks into weapons.

Next morning,while completely naked, the two search the island and find the hunters camping on the beach, with an injured Alex sleeping nearby.

Katie Aselton began developing the film in 2011, expressing her interest in directing a thriller that audiences would see as realistic.

[4] Mark Duplass was confirmed as writing the screenplay and the couple sought to raise funds for the film through crowdsourcing on Kickstarter.

[4] Kate Bosworth and Lake Bell were signed to Black Rock to play Sarah and Lou, with Submarine Entertainment handling sales.

The site's consensus reads, "It springs from smarter ideas than your average chase thriller, but ultimately, Black Rock falls back on disappointingly familiar ingredients".
