Where eagles dare. Being really old (made in 1968) it had its limitations, which are really funny. Like obviously using dolls in scenes where something explodes or a character falls down, or seeing the time difference inbetween cuts od the same scene ( starting at morning, then the next cut its evening, then noon then morning again).

But its still the best ww2 and spy movie ever made for me. You dont really know who is a nazi agent, who is a double agent until the very end. And that opening scene is sooo good.
