Dave Bautista and Rupert Grint Star in Trailer Psychological Horror Film Knock At The Cabin

Dave Bautista and Rupert Grint after rising to fame in heroic roles showed their villainous side in a trailer released on Thursday for the upcoming M. Night Shyamalan apocalyptic psychological horror film Knock At The Cabin.

The trailer showed Dave, 53, who portrays Drax in the Marvel Cinematic Universe, teaming up with Rupert, 34, who played wizard Ron Weasley in the Harry Potter film franchise, teaming up to terrorize a family.

The trailer opened with picturesque views of a log cabin and a green forest as gay dads Andrew and Eric, played by Jonathan Groff and Ben Aldridge, drove in a car with their daughter Wen, played by Kristen Cui.

The happy family sang along to the upbeat disco/funk song Boogie Shoes by KC and the Sunshine Band and were shown enjoying their family getaway in the woods.

Wen was working on her butterfly project when she noticed a man deep in the woods and looked at him worryingly with a furrowed brow.

Andrew and Eric then heard a knock on the cabin door and looked over their shoulders.

A tattooed hand was shown reaching down as Wen's fingers reached up to shake hands with Dave's character.

'My name's Leonard. It's nice to meet you, Wen,' Leonard said.

'Why are you here?,' Wen asked him.

'I suppose I'm here to make friends with you and your dads, too,' Leonard replied.

'But my heart is broken,' he added.

'Why is it broken?,' Wen asked him.

'Because of what I have to do today,' Leonard said ominously.

Wen was then shown with Andrew and Eric who armed themselves after watching strangers approach from the woods.

'There is a woman carrying something that looks like a pick with a chain and a mallet head,' Eric said after peeking out a window.

The knocking continued as the family looked terrified and Wen was shown being followed home.

'You see, the four of us have a very important job to do. In fact, it might be the most important job in the history of the world,' Leonard said in a voice-over.

Eric and Andrew tried to barricade the cabin and armed themselves, but were easily subdued by Leonard and his companions Adriane, played by Nikki Amuka-Birdc, Sabrina, played by Abby Quinn, and Redmond, portrayed by Rupert.

Leonard was flanked by Sabrina, Adriane and Redmond as he addressed their captors after the home invasion.

'We were called and are united by a common vision, which has now become a command that we cannot ignore,' Leonard told bound Eric and Andrew.

'The four of us are here to prevent the apocalypse. Your family has been chosen to make a horrible decision,' he continued.

'If you fail to choose, the world will end,' Leonard said as the screen turned black.
