I can call up a number of early films and shorts by famous directors that aren't even 1/10'th as good as what Alex did. So far, it's a good start and I wouldn't be surprised if this young man has a major career ten years from now.
Don;t blow all your money if your not sure what you want. A Nikon 5500 or the new Rebel and a Mac with Final Cut Pro or Premiere is a greatway to start out. The great thing about DSLR's is you can both learn stills photography( which is the best way of understanding the nitty gritty of exposure) and videography all at the same time. I wouldn't even get expensive lights yet, just maybe some clamp lights or some PAR's if you have the urge to start playing with lights. Then and only then if you wanted to move up, I would look into better gear if you really feel like you need it( like those upcoming Blackmagic cameras).
