I have not seen the movie, but I'd like to. I've been in the church where those men died a bunch of times. I lived in Prague for 9 years growing up, and my dad was big into WWII history. He'd take everybody who came to visit to that church...it was part of his orientation tour to the city...so we went there a lot. It's just around the corner from Karlovo Namesti metro station in Prague, and you can still see the pock marks from bullets in the concrete around the window to the basement where they were hiding. They fought hard, and the Nazis ultimately ended up flooding the basement with a fire hose. Inside the church is kind of a mini-museum, with actual photos of the assassination site, and the assault on the church.
I've also been to the area where they blew up Heydrich, although it has changed a bit since the 40s. The man was truly a POS and needed to die, but the cost was pretty extreme.
It's a sad story, as they all died in the end, but those guys had to know that was very likely when they undertook it, and the bravery that they showed was remarkable. The really horrific part, though, was what the Nazis did to several villages in retaliation. They found out that some of the resistance guys had family that lives in a couple of small villages outside the city. They shot all the men, gassed the children, and sent the women to camps, then bulldozed the villages to the ground. There's nothing left now but memorials. Truly sick and despicable people.
IIRC, after the war they hanged the guy who betrayed them to the Nazis. That doesn't come close to making up for the damage he wrought, though.
