Our favorite Allentown actress, Amanda Seyfried (“Mamma Mia” and the upcoming “Dear John” and “Chloe”), will be leaving the HBO series “Big Love” to become a full-time movie star.

“She’s been exploring her movie career for a couple of years now, and we’ve been giving her a lot of room to do that,” “Big Love” creator Will Scheffer told TV Guide. “I know having a commitment to a show for six months definitely cuts into her ability to pursue that career.”

Spoilers under the cut!

Before she leaves, however, Amanda’s character, Sarah, will get married.
