The Munich Agreement, which gave part of Czechoslovakia to Adolf Hitler in 1938, is the subject of a newly released film now streaming on Netflix. “Munich: The Edge of War,” starring Jeremy Irons as British Prime Minister Neville Chamberlain, debuted on Jan. 21 and is already in the top 10 in many countries, including the Czech Republic. It has garnered good reviews, with an 84 percent rating on Rotten Tomatoes. It does, though, play a bit freely with historical facts.
