Breaking Dawn Part One & Two, IMDB Rumors!

The first is over on the Breaking Dawn Part 1 page — Xavier Samuel is listed as a cast member for Riley (Who was killed off in Eclipse) -

.
IMDB is user based, and the information can be changed without verification. However, Riley may be in part 1 of Breaking Dawn for flashbacks, or perhaps new dream sequences Bella may have.
The second interesting update comes from the Breaking Dawn part 2 IMDB page. There is already an actor listed as rumored to play the part of Eleazar -

Michael AvMen is a fairly unknown actor. Whether or not he is a contender for the part of Eleazar, we have no idea. Like I said before, this is listed as a rumor, and could have been changed by a user to create buzz.
