Hmmm....eenie, meenie, minie, moe....
I think my favorite is "Battleground", the WWII movie about the Battle of the Bulge with Van Johnson, Ricardo Montaban, and the incomparable James Whitmore playing the crusty sergeant. The movie came out in 1949 and it made a big impression on me. Of course, we kids were constantly reinacting the movie. Then it snowed. In Texas! One of those rare occurrences, but it snowed. Oh, boy! Dust off the lines for "Battleground" and let fly with your imagination! One could really get into the role since we had real snow and gee whiz! - was it ever cold. "Band of Brothers" is in a class by itself. The excellence of this series sets it apart from all the others. But if you're talking regular Hollywood movies, those made before "Band of Brothers", then I have to go with "Battleground."
