Not that this is going to be a surprise to anyone, but Robert Pattinson (Who plays Edward in Twilight) has confirmed that they are going to be shooting a fourth Twilight film that follows the final book in the series.

The one hold up is that Robert Pattinson has become a very hot commodity and has signed on to a lot of film projects, so fitting the shooting of the final Twilight movie into his schedule is going to be something of a challenge. He’s already doing Twilight 2 and 3 and has no less than 3 other projects set to start filming as well. So how long do they wait to shoot it?

They seem to want to do the Harry Potter things and have one out each year, but hat might not be possible for Twilight 4. They may have to wait a little bit. The Hollywood Reporter gives us this:

Robert Pattinson, who shot to stardom in “Twilight” and is now filming the second and third movies in the franchise, confirmed Tuesday in Cannes that there will be a fourth installment of the vampire franchise based on the book “Breaking Dawn.”

Pattinson told The Hollywood Reporter that he is committed to starring in the final outing to date but doesn’t know when backers Summit Entertainment will begin production because of the actor’s jam-packed shooting schedule. Fans have been hoping for a movie version of the fourth novel from Stephenie Meyer’s best-sellers, so Pattinson’s commitment is the biggest fillip yet. The fourth book (caution — spoiler alert) centers on Bella and Edward’s marriage and her subsequent pregnancy.

Dropping in on the Croisette on the way to shooting the final four days of “New Moon” in Italy on Friday, Pattinson said he is heading back to Vancouver in October to finish up “Twilight: Eclipse,” the third installment. In between, the British actor, who turned 23 last week, plans to star in “Remember Me,” which Summit also is producing.
