The plot has plenty of cameos from characters like Lee (who is hilarious), Lei, and Ganryu. Don't expect everyone to appear however, as the movie doesn't follow a tournament plot line. I admired this idea, as most fighting game animes or films try to cram in every character and it always seems too forced for my liking. Keeping the cast down to a select few allowed for more character exploration and a descent story. Don't go into Tekken: BV expecting Shakespeare, but it is certainly better than the recent Tekken live action film or any Uwe Boll nonsense.
The movie has plenty of funny scenes. Panda has her shining moments but the show stealer is the Mishima misfit, Lee. He is a teacher and odd caretaker for school girls, Alisa and Xiaoyu. His lines are delivered in a superbly aloof manner, and the audience cracked up whenever he appeared. Unfortunately, the movie also has plenty of unintentional humor from poorly written dialogue.
