London, Feb 19 - Actress Kristen Stewart doesn't want to give final word till part four of "Twilight" movie goes on the floor.

"I have been told to be ready for November. I mean, it looks like a 'yes' but it's still not concrete," contactmusic.com quoted her saying.

Kristen feels novel should be split into two films because a lot happens in the final book.

"It absolutely warrants being two films. It would be hard to cram all of it into one movie," she said.

The first two movies "Twilight" and "The Twilight Saga: New Moon" were huge box offices smashes and the third instalment, "The Twilight Saga: Eclipse" is expected to repeat the same success story.
