If anyone here a fan of Batman films or really good fan filming,I recommend this site. link
But just in case the links take too long on some of them,here are some easier shortcuts to watch them on google. link
That one's for Batman Beyond Year One. link
This one is for Batman-Dark Justice starring a real kick ass Batman in it. link
This last one I recommend the most cause it stars a truly cool,unique and frightening Joker in it that imo should be in the upcoming sequel to Batman Begins. Check it out...but not by yourself.
In case the links don't work,just try the original site adress and trust me there worth downloading in the end.
Enjoy!
