There is a wave of new excellent, not that short youtube movies recently, here are the ones I recommend.

DRONE - http://www.youtube.com/watch?v=u8PzkGM60Lc&list=PL6BF5DAE7D4915461&feature=plcp

Halo 4: Forward Unto Dawn - http://www.youtube.com/watch?v=BfJVgXBfSH8&list=SPAE1F854F00D8E6AC&feature=plcp

Battlestar Galactica - Blood and Chrome - http://www.youtube.com/watch?v=pT79x4qM4FE&list=PLrFaRFw9s4G4OYkHPs0afqM_nT0jLvvPy&feature=plcp

 

Gone with the Blastwave - https://www.youtube.com/watch?v=TY2xw6u6n5k
If you dislike the vostfr captions, here is the original version: http://vimeo.com/17054326

It is not recent, but it is not really well-known either. It is of a lower quality than those you posted too. It is the only one I know on youtube though. Vimeo usually is the one to contain good amateur films.
