"The Chain Gang" is a black & white cartoon from Disney. While you might see it floating about in color, it's been colorized...and isn't as pristine looking as some of the colorized early Mickey cartoons.
The first thing I thought when I watched this one was "How in the heck would Mickey end up in prison?!"! After all, although Chaplin and Laurel & Hardy did some comedies set on a chain gang, this is Mickey Mouse....the internationally beloved cartoon character here!! Well, you never actually learn why he's in prison and he spends much of the film trying to escape....and Pegleg Pete is bent on keeping him there.
Compared to other cartoons of the day, this one is superior. But it's also a bit grim and not quite right....mostly because you just cannot picture good old Mickey committing crimes! Weird...but watchable.
