Sometimes truth is stranger than fiction, and there are many interesting films of this or last year which are based on true stories, including Mank, The Trial of the Chicago 7, The United States vs. Billie Holiday, Tesla, Hillbilly Elegy, The Dig and The Mauritanian. Crime and war films are often inspired by real stories (Catch Me If You Can , The Pianist ) and I previously compiled a list of 25 “Must-See” Biographical Films (see also my related list of 5 Great Films About Adventurers Based on Real Stories). Below are five films which were based on, or inspired by, real stories which, in turn, are simply remarkable.
I. The Sound of Music 
The Sound of Music, starring Julie Andrews and Christopher Plummer, might have been a book and a theatrical musical once, but it was also based on an incredible true story. In her memoir titled The Story of the Trapp Family Singers , Maria von Trapp tells the story of her family who originally came from Salzburg, Austria, but who were then forced to cross borders and emigrate to America to escape Nazi persecutions in Europe.
Even though the true story was dramatized substantially for the film, it remained true in essence. So, in reality, a young woman from a religious background did come to work in the Trapp family, but not as a governess, but as a tutor to one of the children (who were in reality ten in number, not seven as in the film). Georg von Trapp was the father in the family, and Maria (as this was the name of the woman/the author) came to love the children first (and only then the father) (source). Georg, who was in reality a much kinder person than in the film, did marry Maria, and the family eventually travelled to Italy and America, and not to Switzerland as in the film. The Sound of Music is also not the only film to be based on Maria von Trapp’s memoir. Previously, Wolfgang Liebeneiner directed a German film The Trapp Family , which was also based on The Story of the Trapp Family Singers.Read more
