A sequel of sorts to "The Longest Day," (same director, some of the same actors like Fonda playing different characters), this is one of the best restorations of a film I've seen in recent years. The picture and sound have been digitally remastered and 17 minutes of previously-unseen footage has been added (you even get a hilarious 1960s intermission card onscreen halfway through, how's that for restoring everything!). The film looks and sounds brand new again and there are new things to enjoy.
Having said that, the film itself doesn't do justice to the real Battle of the Bulge or Ardennes Offensive as it is also called. The real battle was fought in blizzard conditions, there are scenes in this film that look like summertime with not a flake of snow in sight. The tanks are also not the gigantic German Tiger and King Tiger tanks that were used in reality. Of course, it was hard to find all the real elements when making this movie 21 years later, but I'd love to see a Saving Private Ryan-style remake where they could put realistic-looking Tiger tanks in with CGI.
Robert Shaw gives a strong performance, even if he does look like the stereotypical bleach-blond, blue-eyed Nazi. The Malmedy Massacre is well-handled, which is unusual for a film from 1965. There are also some interesting black-and-white interviews and "Making Of" documentaries from the time included on the DVD.
I don't think the average viewer will worry about the historical inaccuracies too much. They'll just see an entertaining, old-school, all-star Hollywood war epic of the kind they don't make anymore. Recommended.
