Oh jeez... I bet you are underwhelmed at the making of an action movie from Asimov's masterpiece. I refuse to pay to see the movie after they butched the whole point of "I, Robot". Hell, they just bought the name after the movie was all set up so they could try to entice Asimov fans to the theater. It just ended up pissing them off.
Put it to you this way, from all I've read the movie has VERY little relation to the book. For one, Susan Calvin is in her 60s in the book.
