Carrie-Anne Moss wanted so much to do this movie, that she twisted her ankle shooting and didn’t tell anyone so they wouldn’t re-cast for her role. As for Keanu Reeves, he lost fifteen pounds to give his character an emaciated look.
Also, after the big shooting scene in the lobby, when the camera moves away we see a large chunk of one of the pillars falling off. This was not planned. But the scene was used in the movie, as it makes a great final for that part.
"popping some bicep tendons out of their sockets"
Somebody needs a physiology lesson.
umm......maybe an anatomy lesson too?
I can forgive a little anatomy confusion... but tendons are attached to the joints, and it's not hard to imagine them tearing near the joint.
