I, Robot - the movie (trailer's online)

Just had a look at the trailer for Asimov's new movie, I, Robot, at
http://www.themoviebox.net/movies/2004/IJKLM/I-Robot/trailer-page.html

Wow, Asimov could sure write an action-packed
robots-run-amuck-and-kill-people cop story. Guess they had to wait
until now to film it since only now with CGI can we have convincing
swarms of robots scuttling around jumping out of shadows at our
heroes, who fortunately are heavily armed and can blow them to pieces
with shotguns.

I couldn't tell if any of the extras in the background of some of
those lab scenes might be Susan Calvin, anyone know if her character
was cut?

myself.

From dim memories, the books played much like an SF version of "Columbo".
