Here is an excellent book to expand your cartoon knowledge. It's called "Tunes for 'Toons: Music and the Hollywood Cartoon". It covers the work of Carl Stalling and Scott Bradley, and also the use of jazz and classical music in cartoons.
I love this cartoon most of all because of its incredible score by Scott Bradley, the MGM composer. His scores are much more subtle than those of Carl Stalling.
This cartoon is also very atmospheric. I LOVE cartoons that are set at night.
This cartoon is awesome on so many levels. This is probably my favorite stage of Daffy's personality; when he was still crazy but not purely a "wacky" character. My favorite part of the whole thing is when he says, "Do you think I'm a Benedict Whozits, or something?" The poses are insane. Also has tons of smoking and three suicides! It's by far my favorite WB wartime cartoon. Directed by Frank Tashlin.
I love this cartoon because It's so atmospheric. I also love the cat character. I wish he was in more cartoons. It was directed by Bob Clampett and has kick-awesome animation by Robert McKimson.
