Question: Third Man on the Mountain, which inspired the Matterhon Bobsleds at the Anaheim theme park, opened on July 17, 1955, was released in what year by Walt Disney Productions? 
Context: Rail transport can be found in every theme park resort property owned or licensed by Walt Disney Parks and Resorts, the theme park and vacation resort segment of the larger Walt Disney Company.  The origins of Disney theme park rail transport can be traced back to Walt Disney himself and his personal fondness for railroads, who insisted that they be included in the first Disney park, the original Disneyland (a key component of the Disneyland Resort) in California in the United States, which opened on July 17, 1955.  The Disney tradition of including transport by rail in its parks has since been extended to other Disney properties with the opening of Walt Disney World in Florida in the United States, Tokyo Disney Resort in Japan, Disneyland Paris in France, Hong Kong Disneyland Resort in China, and Shanghai Disney Resort in China. Magic Kingdom is a theme park at the Walt Disney World Resort in Bay Lake, Florida, near Orlando.  Owned and operated by The Walt Disney Company through its Parks and Resorts division, the park opened on October 1, 1971, as the first of four theme parks at the resort.  Initialized by Walt Disney and designed by WED Enterprises, its layout and attractions are based on Disneyland Park in Anaheim, California, and is dedicated to fairy tales and Disney characters. Disney's Hollywood Studios is a theme park at the Walt Disney World Resort in Bay Lake, Florida, near Orlando.  It is owned and operated by The Walt Disney Company through its Parks and Resorts division.  Based on an idea by Marty Sklar, Randy Bright, and Michael Eisner, the park opened on May 1, 1989, as the Disney-MGM Studios Theme Park, and was the third of four theme parks built at Walt Disney World.  Spanning 135 acres , the park is dedicated to the facets of show business, including film, television, music, and theatre, drawing inspiration from the heyday of Hollywood in the 1930s and 1940s. Third Man on the Mountain is a 1959 American Walt Disney Productions film set during the golden age of alpinism about a young Swiss man who conquers the mountain that killed his father.  It is based on "Banner in the Sky", a James Ramsey Ullman novel about the first ascent of the Citadel, and was televised under this name.  The movie inspired the Matterhorn Bobsleds attraction at Disneyland Park. Tokyo DisneySea (東京ディズニーシー , Tōkyō DizunīShī ) is a 176 acre theme park at the Tokyo Disney Resort located in Urayasu, Chiba, Japan, just outside Tokyo.  It opened on 4 September 2001, at a cost of 335 billion yen.  Owned by The Oriental Land Company, which licenses Disney characters and themes from The Walt Disney Company, Tokyo DisneySea attracted an estimated 11 million visitors in 2016, making it the sixth-most-visited theme park in the world.  Tokyo DisneySea was the second theme park to open at the Tokyo Disney Resort and the ninth park of the twelve worldwide Disney theme parks to open.  Tokyo DisneySea was the fastest theme park in the world to reach the milestone of 10 million guests, having done so in 307 days after its grand opening.  The previous record-holder was Universal Studios Japan 338 days after its opening. Disneyland Paris, originally Euro Disney Resort, is an entertainment resort in Marne-la-Vallée, a new town located 32 km east of the centre of Paris, and is the most visited theme park in all of Europe.  It is owned and operated by The Walt Disney Company and is the only resort outside the United States to be.  The resort covers 4800 acre and encompasses two theme parks, many resort hotels, a shopping, dining, and entertainment complex, and a golf course, in addition to several additional recreational and entertainment venues.  Disneyland Park is the original theme park of the complex, opening with the resort on 12 April 1992.  A second theme park, Walt Disney Studios Park, opened in 2002.  The resort is the second Disney park to open outside the United States following the opening of the Tokyo Disney Resort in 1983. Disney's Celebrate America is a seasonal fireworks show that premiered on July 3, 2008 at the Magic Kingdom theme park in the Walt Disney World outside Orlando, Florida, and on July 4 of that same year at Disneyland in Anaheim, California.  The 15-minute show, produced by Walt Disney Creative Entertainment under creative director Steve Davison, celebrates the traditions, spirit and music of the United States of America, and is shown in lieu of the regular fireworks shows on both July 3 and 4 at Walt Disney World and Disneyland.  While both parks use the same soundtrack, the fireworks used are different, due to Anaheim's fireworks laws being more strict. Disneyland Park, originally Disneyland, is the first of two theme parks built at the Disneyland Resort in Anaheim, California, opened on July 17, 1955.  It is the only theme park designed and built under the direct supervision of Walt Disney.  It was originally the only attraction on the property; its official name was changed to Disneyland Park to distinguish it from the expanding complex in the 1990s.
