This is another of those war movies that while it may be old, still stands the test of time against some of the new kids on the block. It's the classic story of a small commando team infilitrating the lair of the Nazi's ala Guns of Navarone and basically kicking the c*** out of anything that goosesteps.
If the body count of this movie was representative of every engagement fought in WWII then they should have just cloned Clint's character and set him loose because he pretty much wipes out a small army.
Leaving the Ramboesque moments of Clint's character aside we still have a great turn by Richard Burton, one of the classical old school actors and a movie full of guns, gals and explosions. What's not to love?
