Indeed. Open Movies are a great learning experience for everybody. With the ability to download all the production files and then study each and every scene, prop, rigs, textures is a big advantage.
I myself am downloading the production assets used on BBB from the following link and studying them.

I have been using it for 7 years now as a hobby and it has been an enriching one.
Hats off to open movies and open source.
