I was going to say you should use Schindler's list, but I forget whether he had an accent in that movie or not. But definitely batman begins, he also did the voice in the video game it says here on Imdb, and oh I didn't know he was in gangs of new york, but everyone had some fake accent in that so that's no good I guess, ah look here... I actually own the movie Next of kin for whatever reason, maybe it's to watch it and let you know if Neeson said anything in it that could be worth using... hmmm
