One of the very first roles I had ever seen Christian Bale in aside from playing Batman. At the time, it was astounding to me that someone would physically transform themselves to such an extreme extent for a movie; I had never quite seen anything like it. I've seen this many times since then, and I always find both Bale's performance - and the film itself - to be equally fascinating and disturbing, and it has continued to hold up very well on rewatches over the years.
Bale has become one of my favorite actors ever since my first viewing of The Machinist, and this remains one of my personal favorite roles of his. The film has a perfect eerie quality and atmosphere throughout, and, as I've mentioned in previous reviews, I love mind-fuck films. This is no exception.
