The Twilight Zone Tower of Terror at Disneyland Paris' Walt Disney Studios Park is based on the same designs as the version at Disney California Adventure Park. However, these designs were originally imagineered for the Paris park at the same time as Tokyo DisneySea's tower, and planned to open just two years after the opening of the park itself.[17] When financial troubles again hit Disney's Parisian resort, the attraction had to be put on hold. In the meantime, it was constructed at Disney's California Adventure as an additional crowd-puller. The attraction was finally greenlit in 2005 and was under construction right in the center of the park, behind the La Terrasse seating area, in early 2006. Upon completion, it was joined by a new themed development producing an outdoor Hollywood Boulevard of faux movie sets.[18] Unlike its American cousins, the Paris Tower was constructed using concrete rather than steel due to French construction guidelines and standards, at a total cost exceeding €180 million.[19] The Paris and California versions were originally believed to become identical versions upon completion, but some differences remain, notably the height of the building, the location of some rooms backstage as well as other differences due to construction and work regulations being stricter in France.[20] The name of the attraction in French is La Tour de la Terreur - Un Saut dans la Quatrième Dimension (The Tower of Terror - A Jump into the Fourth Dimension). The default language for the pre-show library video and the ride is French, but can be changed to English by the Cast Member upon request. The library video is the same as the American version, but is dubbed in French and subtitled in English. The Twilight Zone Tower of Terror, commonly known as Tower of Terror, is an accelerated drop tower dark ride located at Disney's Hollywood Studios, Disney California Adventure, Tokyo DisneySea and Walt Disney Studios Park in Paris. Exempting the Tokyo version, all the attractions are based upon Rod Serling's CBS television anthology series, The Twilight Zone, and take place in the fictional Hollywood Tower Hotel, in Hollywood, California. The Tokyo version, which features an original storyline not derived from The Twilight Zone, takes place in the fictional Hotel Hightower. Nevertheless, all four versions place riders in a vehicle themed as a seemingly ordinary hotel elevator, and present riders with a fictional back story in which people mysteriously disappeared from a hotel elevator under the influence of some supernatural element many years prior. The original version of the attraction opened at Disney's Hollywood Studios (at Walt Disney World in Florida) in July 1994, and was the basis of the 1997 made-for-television movie Tower of Terror where several scenes were shot at the actual attraction. A decade later, Disney began plans to add similar versions of the attraction at their newest parks at the Disneyland Resort in California, Tokyo Disney Resort in Japan, and Disneyland Resort Paris; in California and Paris, Disney sought to use the popular attraction to boost attendance at the respective resorts' struggling new theme parks. The California and Tokyo versions of Tower of Terror opened in 2004[5] and 2006,[6] respectively, while financial problems delayed the opening of the Paris version until 2008.[7] The Tower of Terror buildings are among the tallest found at their respective Disney resorts. At 199 feet (60.7 m), the Florida version is the second tallest attraction building at the Walt Disney World Resort, shorter only than Expedition Everest's 199.5 feet (60.8 m). At the Disneyland Resort, the 183-foot (55.8 m) structure is the tallest attraction at the resort, as well as one of the tallest buildings in Anaheim.[8] At Disneyland Paris it is the second tallest attraction.
