According to Cinematical.com, Taylor Lautner the original ‘Jacob’ from the first Twilight movie will be returning for the sequel “New Moon”. It was widely rumored and speculated that new Director Chris Weitz was looking to replace the actor because of the character Jacob’s much bigger physique and older look in the new movie.  I guess it has now been confirmed that Taylor Lautner, through some heavy campaigning and the promise of ‘beefing’ up for the next Twilight will be cominng back.
