Based on a comic: It is based on the Red comic book series by Warren Ellis and Cully Hamner.
Stellar Cast: The cast includes Bruce Willis, John Malkovich, Mary-Louise Parker, Anthony Hopkins, Helen Mirren, Catherine Zeta-Jones, and Lee Byung-hun.
Filming Locations: Filming began in Montreal, Canada, in late September 2012, before moving to Paris and London. Montreal was chosen partly for tax credit reasons and its ability to double for European locations, with some scenes set in London actually filmed there. Other locations included Dunsfold Aerodrome and Hedsor House & Park in England, and the Hôtel de Crillon in Paris.
Lee Byung-hun's Personal Touch: A childhood photo of Han Cho-bai (Lee Byung-hun) and his father in the film are real photos of the actor and his late father. Lee's father's aspiration to be an actor led director Dean Parisot to include him in the end credits as a tribute.
Ernest Borgnine's Wish: Ernest Borgnine, who was in the first RED movie, hoped to be in the sequel and carry a gun, but he passed away before production. His role was rewritten and played by Titus Welliver.
Malkovich the Wine Connoisseur: John Malkovich is a wine connoisseur, which is referenced in the movie when his character uses wine to find another character.
Gun Law Constraints: U.K. gun laws restricted the types of guns the production team could use.
Box Office Performance: The film grossed $148.1 million worldwide against an $84 million budget, making it a commercial success, although its North American opening weekend was lower than the first film.
Critical Reception: Reviews were mixed, with praise for the cast and action but some criticism regarding the plot and lack of the original's charm.
