Anyone gone to a Film & Production School or related (screen writer)?

At this time, I'm currently thinking about taking up some type of Film/Production/Screenwriter course in the possible future as an alternate plan to my current one. Course would include me with a small group of other students to be the whole filming/production crew to make films. But starting more back, I've been told I have some creative writing/practical ideas that would be perfect to film thus taking a course to improve and learn on the real writing that happens. Well... I want to make smart scripts and not repeat some of the brainless and/or retarded ideas in the film industry now. Basically, show the world smart filming and good screen writing (along side with the very few there are today).
Just would like to know if anyone is or anyone knows someone that has taken a course to see how its like so they can help me further or discontinue my possible dream.

Plan to start as early as next year if the decision is made. I promise to make good films/scripts.... AND... want to be the first major writer that actually listens to the public and make what they want (the smart ones).
