Well, Windows Movie Maker isn't the same thing as The Movies. If you're looking for something similar that lets you use animations to create movies, then try either Moviestorm or iClone. To make anything worthwhile, you'll probably have to end up spending a lot more than you'd like on both, but iClone is a lot more expensive and isn't a free download like Moviestorm.
Also bizzarely, some people seem to be directly ripping Starmaker faces from The Movies
here.
Magix Movie Edit Pro is a relatively cheap yet powerful editing tool for movies, which I use. You're not going to find anything worthwhile for free though, so if that's what your budget is you're best sticking to Windows Movie Maker.
The only thing worse than beating a dead horse is betting on one.
