Was very fond of Woody Woodpecker and his cartoons as a child. Still get much enjoyment out of them now as a young adult, even if there are more interesting in personality cartoon characters and better overall cartoons.Despite being an Andy Panda cartoon, 'Knock Knock' is significant for being Woody's debut, and, while he was basically a supporting character (it was his next cartoon 'Woody Woodpecker' where he first properly qualified as a lead), it made him a breakout star and no wonder. He is enormous fun to watch and has all the best and funniest moments in 'Knock Knock', and while with some different character traits to the Woody Woodpecker one is more familiar with there are also parts of his personality that are recognisable.Andy Panda is a nice, cute and appealing lead character, if a little bland especially when compared to Woody. So much so 'Knock Knock' would have perhaps been even better with him in support and Woody as the leading character, and it's once Woody is introduced that the cartoon properly comes to life. The father is fun too.For so early on for Woody Woodpecker, the animation in 'Knock Knock' is mostly very good. The one exception is the character design of Woody, the design itself is a little odd and the drawing compared to later was pretty ugly. Otherwise, the colours are rich and vibrant and the backgrounds meticulous in their detail.Love the music too. It's characterful, lushly orchestrated and is not only dynamic with the action it even enhances it. The writing is suitably witty and raises a number of chuckles, while the never less than amusing and beautifully timed sight gags are even more impressive especially in the parts where Woody is on the rampage.'Knock Knock's' voice acting is strong, with as ever impeccable work from Mel Blanc, even though the later voice actors were more familiar to me.In summary, very good fun, more than just historical interest. 8/10 Bethany Cox

Woody Woodpecker is one of my favorite cartoon characters, and this is one of his best cartoons. It is also memorable for being Woody Woodpecker's first cartoon. Keep in mind that this is a little more of a prototype version of Woody than the Woody Woodpecker that we know and love today. Although Woody Woodpecker is often remembered for being a screwball character, he is much crazier in this cartoon than he is in his later appearances. He also looks kind of ugly in this cartoon, with giant buck teeth and ruffled, bent up feathers. Woody is a little more aggressive in this cartoon as well, and is actually the antagonist in this cartoon rather than the protagonist. He chugs an entire mug of beer in two seconds at one scene, and, as it turns out at the end of the cartoon, actually belongs to a mental institution! However, beneath all of this raucous behavior that the woodpecker is involved with in this short, Woody is still the innocent little woodpecker that he is in his later cartoons. There are many great gags in this cartoon, as well as Mel Blanc's incredible voice acting skills with Woody Woodpecker. I would recommend people seeing a few other Woody cartoons before seeing this one, simply because Woody is not completely developed in this short, but once you do see this cartoon, I guarantee that you will laugh a lot.

Woody Woodpecker's screen debut, as others have pointed out, was really an "Andy Panda" cartoon but Woody apparently made such a strong impression that he went on to be a animated movie star."Can you really catch a bird by putting salt on its tail? That's the question asked, and how we are introduced to WW. Little Andy had asked the question to his dad, who was busy reading the day's Racing Form (which was filled with puns. Take the time to freeze the picture and you'll get some laughs or groans.)The rest is kind of juvenile but that had to be the intended audience, at least early on. Also, it's 1940 and humor - especially with cartoons, in my opinion - got much better - by the middle of the ''40s. Early Tom & Jerry cartoons, Daffy Duck, Bugs Bunny, etc., all didn't hit their prime until then.

Happens all the time-a seasoned pro gives a young unknown a break and it makes the unknown a star! Woody went on to eclipse Andy Panda in popularity and was the top draw for Lantz studios in the years that followed. But the two always had a cordial, if somewhat bizarre, friendship, appearing in a number of shorts together. They were often seen vacationing together in their off-screen time, unlike well-known rivals at two other major studios and retired together with their families somewhere in California. Great short that's lots of fun. Well worth tracking down. Highly recommended.
