A Disney classic from the peak of their 1950's golden age, 'Lady and the Tramp' narrowly misses out on 4 stars from me, not because there's anything wrong with it, but only because there are still some other movies around I like more - and what would I give them?
This was also the start of Disney's 'talking animal' period, which lasted almost uninterrupted for nearly 35 years, until 'The Little Mermaid'.
The animation is beautifully done. Especially impressive is the brilliant intergration of completely realistic canine body movement with anthropomorphism. Of course all animated animals are a mixture of realism and anthropomorphism to some degree, but in Lady and the Tramp, the characters manage to be very realistic and very cartoony at the same time - sometimes more one than the other, as in the famous spaghetti scene, but the two are always kept in careful balance.
There are a few, only a few weak spots: the story is just a little fluffy for my tastes, and the end does seem a little rushed: Tramp is simply intergrated into the upper middle class household and he has no problems with this? Well, at least his son does, 45 years later. But you have to remember the movie was made in 1955, and it's difficult to be too hard on it for its soft focus. It's also a large part of its charm.
The music is well above average (I don't know if it's just me, but it only seems to be in the last couple of decades that Disney have started writing instantly forgettable songs.)
Significantly, the songs are carefully integrated into the narrative flow of the story, so that instead of characters going into a song and dance routine, or, alternatively, having everything suspended for several minutes while a number is played over the top of proceedings, most of the songs seem to be a free-flowing extension of the characters' actions, such that you don't get that "uh-oh, here comes a song" feeling. Also, there are a pleasingly modest number of songs overall.
The story is very well paced the voice characterisations all excellant, even if a few of them them stereotyped now. The movie also still has a quite modern look to it, considering its age. There are just glimpses of Disney's earlier character design style, usually in Lady's facial expressions, but they are fleeting. For the most part, visually, the movie could have been made any time up through the 80's - though the soundtrack does have an old-style Disney feel to it.
It must have been amazing fifty years ago. Even today, it's impressive and charming.
footnote: a sad coincidence: I watched this movie for the first time in years, a couple of days before Frank Thomas, the guy who animated the 'spaghetti scene', and who appears in the bonus interviews, passed away.
