Sundance: Keanu Reeves Makes Two Enticing Friends in 'Knock Knock' Teaser

Eli Roth unveiled the preview of the thriller before its Sundance premiere.

When the wife and kids are away, Keanu Reeves will play.

Reeves stars in Knock Knock, a tale of a father who lets two nubile and willing ladies into his house one rainy night while his family is out, only to find his guests unwilling to leave and with plans of their own.

The film, which modernizes Peter Traynor’s 1977 film Death Game — also features Lorenza Izzo, Ana de Armas, Aaron Burns, Ignacia Allamand and Colleen Camp.

Director Eli Roth revealed the teaser on Facebook in conjunction with the film's midnight premiere on Friday night at Sundance Film Festival, at which Roth told buyers and movie watchers that the film "marks a turning point in my life."

Reeves also lightheartedly noted during the film's post-screening discussion that he felt very much like a sacrificial lamb with his character: "I was the sacrifice for this very cautionary tale."
