Pirates of the Caribbean: On Stranger Tides is a 2011 American fantasy swashbuckler film, the fourth installment in the Pirates of the Caribbean film series and a standalone sequel to At World's End (2007). It is the first film in the series not to be directed by Gore Verbinski, replaced by Rob Marshall. Jerry Bruckheimer again served as producer. In the film, which draws its plot loosely from the 1987 novel On Stranger Tides by Tim Powers, Captain Jack Sparrow (Johnny Depp) is joined by Angelica (Penélope Cruz) in his search for the Fountain of Youth, confronting the infamous pirate Blackbeard (Ian McShane). The film was produced by Walt Disney Pictures and released by Walt Disney Studios Motion Pictures. It was the first film in the series to be released in the Disney Digital 3-D and IMAX 3D formats.
Writers Ted Elliott and Terry Rossio first learned of Powers's novel On Stranger Tides during the back-to-back production of Dead Man's Chest (2006) and At World's End, and considered it a good starting point for a new film in the series. Pre-production started after the end of the 2007–2008 Writers Guild of America strike, with Depp collaborating with the writers on the story design. Principal photography lasted for 106 days between June and November 2010, with locations in Hawaii, the United Kingdom, Puerto Rico and California. Filming employed 3D cameras similar to those used in the production of the 2009 film Avatar, and ten companies were involved with the film's visual effects. Following inflated production costs which ballooned the net budget to $379 million, the film currently ranks as the most expensive film ever made.
The checkered past of Capt. Jack Sparrow (Johnny Depp) catches up to him when he encounters Angelica (Penélope Cruz), a beautiful pirate that Jack once loved then left. Angelica forces him to accompany her to the Queen Anne's Revenge, the ship of the notorious Blackbeard (Ian McShane). Accompanied by a zombie crew, the trio sets sail to find the legendary Fountain of Youth. However, Jack's rival, Barbossa (Geoffrey Rush), also seeks the fountain, as does a ship from Spain.
