The process of creation goes on all the time. When I get through, I feel I know what the character will do in every situation. But the building up of the part is not mechanical or deliberate. It grows out of the text.
The play is on top of me all the time, and I am constantly thinking about it. Even when I leave the theatre, I'll mumble the lines to myself or think about the way the character walks or holds himself.
The first Halloween was very well made. The second one was also well made, though I didn't like it as well as the first one. The third one had nothing to do with the series at all and perhaps shouldn't have been made at all.
Loomis has always felt himself responsible for the fact that he did not stop Michael when he first murdered his sister, and so he's got that guilt to live with.
John Carpenter created the idea of Halloween, so his vision remains the most focused and intelligently directed of the series. The directors that have followed have kept the original intent of the concept.
John and I had a few meetings about what direction the sequel should take. I made some real insane suggestions. True to what you'd expect, he ignored them all and just picked up Halloween II where the original left off.
