Saw a film a few years ago titled "Operation Daybreak" on UK television - date of release was mid 70's. A fairly accurate portrayal of the assassination of Reinhard Heydrich in Prague, 1942 and its aftermath. In English, the cast mostly English/US but some Czech actors. See www.imdb.com/title/tt0075019/ for more info. Apart from obvious landmarks (Stare Mesto etc), Resslova Street (covered traffic signs) and the Church of Sts Cyril&Methodius seemed to be the actual locations. Set of the church interior looked as if filmed in real location, but explosive damage etc during filming would seem to contradict this. Does anyone have any more information?
