Sometimes they are big, sometimes they are small.
And sometimes (as in
Vertical Limit) the role becomes MUCH smaller when the director decides Sid is so effective when he doesn't say anything but just lets his eyes convey what he's feeling that he keeps cutting his lines! Six months work on the other side of the world and exactly six lines of Sid's dialogue made it into the final film!
At least
Reign of Fire wasn't a disappointment. It was what it was and Sid knew that going in.
Another thing about
Reign of Fire that you might like to know is that Gerard Butler learned he'd been cast as the lead in
Timeline during the making of that movie and he and Sid went out drinking together to celebrate. I like to think Sid found a friend and kindred spirit on the set of that movie.
