If you like Christopher Nolans style of Batman films, you'll like this. It stars the Joker (styled off Heath Ledgers performance) and one of his lackeys, whom he has found out is an undercover cop. Dont worry, I havent ruined anything for you. The only thing wrong with this is, I think, the guy who plays Joker, Paul Louis Harrell, licks his lips a little too much. Its supposed to be done as if theres something stuck in your teeth, not honey on your lips or something. Apart from that, the guys who made this did an incredible job for a budget of $800. Dont know if they've made more, but it'd be worth your time researching it. Anyway, this is the link to their site. Enjoy!
Epic, probably my favorite Dark Knight spin-off. I do think Joker's face was a little... clean. And he did lick his lips too much. Apart from that, it is great for a eight hundred dollar film. Also look at this. BATMAN VS. PREDATOR‏ - YouTube
I haven't seen that short film in ages, forgot how cool it was. I now want to go and watch Batman TDK and all three Predators. Damn you, Soul Slasher.
