There are going to be plenty of film packages that spark buyers at Cannes, and here’s a fresh one that isn’t even waiting for the Croisette. Keanu Reeves has just committed to star for Eli Roth in Knock Knock, a psychological thriller that Roth wrote and will direct. Reeves will play a happily married family man who’s left alone for the weekend. Two beautiful girls show up at his house, and turn his life upside down. Those femme fatales will be played by Lorenza Izzo, who just starred for Roth in the September 5 release The Green Inferno, and Ana de Armas, who just played Robert Duran’s wife in Hands Of Stone opposite Edgar Ramirez and Robert De Niro. Ignacia Allamand, who also starred in Green Inferno, plays the man’s wife. Colleen Camp, a catalyst in assembling this film as producer, will also play a role, as will Aaron Burns, who also just worked with Roth in The Green Inferno.
