Trivia: The "MiG-28s" in the movie are actually all Northrop F-5E Tiger II's, an American plane used for training and sold to other countries. In reality, there is no MiG-28.
Suggested correction: It could be argued that in the alternate reality of Top Gun the fictional "MiG-28" was an improved reverse-engineered F-5 (VPAF gave the Soviets access to ex-VNAF F-5:s for evaluation after the fall of Saigon) explaining their similarity.
This isn't a valid correction for a trivia entry. There is no mistake being suggested, just letting viewers with limited plane experience know MiG-28 isn't a real plane.
Trivia: Kim Cattrall was surprised when she got to the set for the prison scene one morning, as no one told her she would be hogtied for the entire scene (in the story, it was due to a deleted scene when she made trouble for her guards). She endured it like a professional, occasionally having her gag removed so she could drink water. When asked by John Carpenter whether or not she was uncomfortable, she simply replied 'I've been in tighter situations than this!'

It is in the National Portrait Gallery, London, England.
Trivia: Willie told Eugene "Muddy Waters invented electricity." Muddy Waters was McKinley Morganfield's [4/04/1913 - 4/30/1983] stage name. Muddy Waters was from Mississippi but relocated to Chicago where he played/fathered "Chicago Blues" and was among the first to use an electric (trified) guitar. Due to how noisy the Chicago South Side was, Muddy need to "amp" the sound of his guitar. Like Willie told Eugene he needed a slide to play the Blues, Muddy Waters wore a slide. (00:34:40)
