Actor Keanu Reeves travels to a murky underworld in the action thriller, "John Wick," playing a grieving husband and retired assassin, who reverts to being a killing machine to avenge the wrongs done to him by Russian mobsters. The film, jam-packed with car chases, gun fights, mayhem and murder, is the directorial debut of Reeves' former stuntman Chad Stahelski and producer David Leitch. As John Wick, Reeves singlehandedly guns down enough mobsters to fill a small cemetery. The film, which opens in U.S. theaters on Friday, is expected to earn an estimated $17 million during its opening weekend. But positive reviews for the Lionsgate R-rated thriller with the feel of a graphic novel and plaudits for Reeves' performance, could boost its numbers against this week's other opener, the horror film "Ouija," predicted to rake in $28 million, according to pro.boxoffice.com.
