Amanda Seyfried, who has played The Henrickson’s eldest daughter on Big Love for the past three seasons, is moving on. Seyfield got her big break as Meryl Streep’s daughter in “Mamma Mia!” last year and now feels that she would like her path to move further in that direction.

In an exclusive interview, TV Guide magazine obtained confirmation of Seyfield’s departure from the show’s creator Will Scheffer. Scheffer told the mag, “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. I know having a commitment to a show for six months definitely cuts into her ability to pursue that career.”

Seyfried will remain in the upcoming fourth season of “Big Love” up until the eighth episode. Her character, Sarah, will get married in the third episode against her parents’ consent and then “move away” in the eighth episode.

The actress, who started her acting career in soap operas like “All My Children”, just finished filming another movie in New York City entitled “Letters to Juliet”.

The fourth season of “Big Love” begins January 10 on HBO. Here’s where you can find episodes of the show online.
