Greatest Showman (2017)
Great musical movie with Hugh Jackman as a main actor... wait, that reminds me of something... Well, nevermind. This one is about Barnum - the showman that brought people the really weird and freaky stuff. And who also wasn't above some swindling.
Now, this was to be expected from musical film, as really, it's all a fabulous show, but goddamn, the usual fact-checking source claims that almost all movie is quite untrue. Well, except for the main line - Barnum opened and operated a literal freak-show museum, which later burned down, so he moved to a proper circus.
Other than that? Barnum financial situation and age are wrong, the whole scandal with opera singer is false, and he was probably not as likeable person as he was portrayed. Also, the whole story of his partner and his feeling for trapeze artist girl is entirely made up, as are both characters. Though, interestingly enough, several of the 'freaks' presented in the movie are references to the actual Barnum performers, including, of course, the famous bearded woman.
So, like some of the Barnum acts, the movie is mostly not true, and does what it does just for show. Still, good show it is.
