Audio problem: In the bar scene where the twins are dancing with the girls, keep an eye on the band in the back. The singer and the guitarist are not always singing and playing in time with the music. Most visible at the end of the scene, the music has the guitar playing a long riff and no vocals, yet the guitarist is barely moving, and the singer is singing with emotion.
Audio problem: When Vincent is receiving the parking ticket for being in the handicap spot, at one point we hear him say "Handicap my ass" but his mouth is not moving. Clearly dubbed in later.
Chosen answer: Although I wouldn't call one a bad guy, Professor Werner is the the one who raised Julius, and would remain a friend because of this bond. Mary Ann (the twins' mother) however, was told that Julius died at birth and was never told about Vincent. She blames Professor Traven for this (probably since he's the only one around to yell at). Vincent on the other hand was never told his mother died during childbirth and he grew up thinking his mother abandoned him. Until Julius showed up, he never knew he was part of an experiment and he had no knowledge of either doctors and probably no feelings regarding either of them.
