Title: It Happened at the World's Fair
Content:  It Happened at the World's Fair is a 1963 American musical film starring Elvis Presley as a crop-dusting pilot. It was filmed in Seattle, Washington, site of the Century 21 Exposition, along with the Seattle World's Fair. The governor of Washington at the time, Albert Rosellini, suggested the setting to Metro-Goldwyn-Mayer executives. The film made $2.25 million at the box office.
Title: Century 21 Exposition
Content:  Events and performances at the Playhouse included Sweden's Royal Dramatic Theatre; a chamber music performance by Isaac Stern, Milton Katims, Leonard Rose, Eugene Istomin, the Claiborne Brothers gospel quartet, and the Juilliard String Quartet; two appearances by newsman Edward R. Murrow; Bunraku theater; Richard Dyer-Bennet; Hal Holbrook's solo show as Mark Twain; the Count Basie and Benny Goodman jazz orchestras; Lawrence Welk; Nat King Cole; and Ella Fitzgerald. Also during the fair, Memorial Stadium hosted the Ringling Brothers Circus, Tommy Bartlett's Water Ski Sky and Stage Show, Roy Rogers and Dale Evans' Western Show, and an appearance by evangelist Billy Graham. The fair and the city were the setting of the Elvis Presley movie It Happened at the World's Fair (1963), with a young Kurt Russell making his first screen appearance. Location shooting began on September 4 and concluded nearly two weeks later. The film would be released the following spring, long after the fair had ended.
Title: It's a Small World
Content:  Fabricated at the Walt Disney Studios in Burbank as Children of the World, it was created by WED Enterprises, then shipped to the 1964 New York World's Fair's UNICEF pavilion, sponsored by Pepsi, where it featured at its entrance a kinetic sculpture, The Tower of the Four Winds, a 120-foot perpetually spinning mobile created by WED designer Rolly Crump. It was added to four attractions — Magic Skyway (Ford), Great Moments with Mr. Lincoln (Illinois), The Carousel of Progress (General Electric), and CircleVision 360 (Kodak)—already under development, which were used by Disney to sponsor, fund, and test concepts and develop ride systems and 
Title: It Happened at the World's Fair
Content:  The Seattle Center, including the Seattle Center Monorail and the Space Needle, serve as backdrops for several scenes. Security officers pursue Presley and the girl through the fountains at what is now the Pacific Science Center. The hitchhiking scene with Elvis and Gary Lockwood was filmed near Camarillo, California, as were some of the flying scenes. The entire hitchhiking scene, up to the point when Mike and Danny are picked up, was filmed on 5th Street near Pleasant Valley Road on the south side of Camarillo. While The Elvis Encyclopedia believes that the Wilburton Trestle was shown in the film, further evidence points to a different location. It is actually a trestle over the White River between Enumclaw and Buckley, now demolished. The view in the film was taken at the intersection of Mud Mountain Road and Highway 410, looking southeast. Mount Rainier is visible in the background, but it cannot be seen at that angle from the Wilburton Trestle, which is larger than the White River Trestle, at six sections high. The trestle pictured in the film is only four sections high at the road crossing.
Title: Chariots of Fire
Content:  The beach scenes showing the athletes running towards the Carlton Hotel at Broadstairs, Kent, were shot in Scotland on West Sands, St Andrews next to the 18th hole of the Old Course at St Andrews Links. A plaque now commemorates the filming. The lasting impact of these iconic scenes (as the athletes run in slow motion to Vangelis's music) prompted Broadstairs town council to commemorate them with their own seafront plaque. All of the Cambridge scenes were actually filmed at Hugh Hudson's alma mater Eton College, because Cambridge refused filming rights, fearing depictions of anti-Semitism. The Cambridge administration greatly regretted the decision after the film's enormous success. Liverpool Town Hall was the setting for the scenes depicting the British Embassy in Paris. The Colombes Olympic Stadium in Paris was represented by the Oval Sports Centre, Bebington, Merseyside. The nearby Woodside ferry terminal was used to represent the embarkation scenes set in Dover. The railway station scenes were filmed in York, using locomotives from the National Railway Museum. The scene depicting a performance of The Mikado was filmed in the Royal Court Theatre, Liverpool, with members of the D'Oyly Carte Opera Company who were on tour.
Title: The World's End (film)
Content:  Principal photography for The World's End began on 28 September 2012. Filming took place in Hertfordshire, at Elstree Studios, Letchworth Garden City, and Welwyn Garden City. Part of the film was also shot at High Wycombe railway station, Buckinghamshire. All twelve pubs in the film use identical signage on menus and walls, reflecting what Wright called "that fake hand-written chalk" common to modern British pubs. The exteriors of the real pubs were shot at locations in Welwyn Garden City and Letchworth Garden City, with altered signage. Letchworth Garden City railway station received a makeover to become the "Hole in the Wall". Stunts were coordinated by Brad Allen, of martial arts film director Jackie Chan's team. Wright said: "In Drunken Master, Jackie Chan has to

Filming resumed on August 3, 2006, at the Bonneville Salt Flats in Utah for 70 days off the California coast, as all the shooting required in the Caribbean had been conducted in 2005. Davy Jones' Locker was shot at Utah, and it was shot in a monochromatic way to represent its different feeling from the usual colorful environment of a pirate. The climactic battle was shot in a former air hangar at Palmdale, California, where the cast had to wear

Guggenheim Museum in New York, but for the shooting sequences a 118 ft wide, life-size replica, including an audio visual exhibition with works of Julian Rosefeldt, was built in Germany. This set was too large for the studio, so it was instead built in a disused locomotive warehouse outside Berlin; its construction took ten weeks. Having filmed in the real museum interior and on the sound stage in Germany, the film crew had to track the lights and camera angles carefully throughout to ensure continuity. The scene includes a sequence in which the protagonist sends a huge art-chandelier hanging from the ceiling crashing to the ground; the entire stunt was created using computer generated imagery.

An overturned Ford Explorer tour vehicle from the original film was initially considered for inclusion in the film, but Trevorrow ultimately settled on featuring the original Jurassic Park visitor center instead. One jungle scene was filmed on a soundstage in Louisiana, while the rest were filmed earlier in Hawaii. On June 30, 2014, Robinson, Simpkins and Greer filmed scenes at Louis Armstrong International Airport in New Orleans.
