Although the show uses footage taken by its film crew for most of the episode shown, aerial footage of various buildings in London is used on "The Apprentice", mainly to acts as small links between scenes and as part of the show's opening credits, and have included shots of the Square Mile and Canary Wharf financial districts, as well as the 180-metre Gherkin, HSBC Tower, One Canada Square, the Citigroup Centre, and the Shard; such locations are not used for filming unless a task involves visiting the site.
