Wow, possibly the worst across-the-board acting I've ever seen.
Zemeckis's early projects certainly don't show a talent for casting-- or comedy. Everybody here is ridiculously over the top in a way that just doesn't work. This was a great idea for a movie, but just like 1941, it suffers from terrible acting, mostly unsympathetic characters, unfunny slapstick, and more unnecessary SHOUTING from everyone than is useful.
The war is not meant to be won... it is meant to be continuous.
