Input: Consider Input: Question: Has the voice actor for the White Rabbit voiced any other characters? Passage:The film follows the storyline of the book closely, save for adding some scenes from Through the Looking-Glass. It also changes the opening real world scene from Alice and her sister sitting at a riverbank to Alice in her bedroom, reluctantly practicing the song "Cherry Ripe", which she is expected to perform at a garden party. (The party guests are played by the same actors as the Wonderland characters and are shown as resembling them in appearance and personality, in a similar manner to the MGM version of The Wizard of Oz. The toys in Alice's room also reflect the residents of Wonderland). Thanks to stage fright and constant nagging from her confident governess (Dilys Laye), Alice runs out of the house and hides herself in the woods nearby, planning to stay hidden until the party has ended. However, an apple floats down from the tree and seems to hover in Alice's face. She is suddenly distracted by a human-sized White Rabbit (voiced by Richard Coombs) rushing by. Curious, Alice follows the White Rabbit, falling down his rabbit hole and ending up in Wonderland.

Input: Consider Input: Question: Which aircraft had a longer operational lifespan in the Royal Canadian Air Force between the McDonnell CF-101 Voodoo and the Avro CF-100 Canuck? Passage:The McDonnell CF-101 Voodoo was an all-weather interceptor aircraft operated by the Royal Canadian Air Force and the Canadian Forces between 1961 and 1984. They were manufactured by the McDonnell Aircraft Corporation of St. Louis, Missouri for the United States Air Force (as F-101s), and later sold to Canada. CF-101s replaced the obsolete Avro CF-100 Canuck in the RCAF's all-weather fighter squadrons. The Voodoo's primary armament was nuclear AIR-2A Genie unguided air-to-air rockets, and there was significant political controversy in Canada about their adoption. Although they never fired a weapon in wartime, the CF-101 served as Canada's primary means of air defence from Quick Reaction Alert facilities at Canadian airbases. The CF-101s were retired in the 1980s and replaced with McDonnell Douglas CF-18 Hornet fighters. Many examples are preserved in museums and parks in Canada and the United States.
