Obviously though the special effects are the main reason to go see this. They are truly amazing. The process in which something becomes invisible or visible is extraordinary. It occurs layer by layer instead of all at once. Skin vanishes, showing muscles.
Muscles disappear, revealing organs and bone.
Organs disappear showing off a full skeleton and then that vanishes. You can expect this movie to be a serious contender for a special effects Oscar. The effects that showed Caine while invisible are similarly impressive. The effects alone make this movie worth seeing. The early parts of the movie are well done and set the mood nicely.
