Fringe has given fans a major reason to tune in on Fridays this winter, one that has nothing to do with witty promos:

The show is casting for Olivia's abusive stepfather. Viewers have never seen this character before, but we've heard plenty about him.

As a nine-year old, Olivia nearly killed her stepdad with a bullet because he was beating on her mom. The man then disappeared, but has been sending Olivia eerie messages every year on her birthday.

Who will play this big bad? Producers have not decided yet. Who SHOULD play him? You tell us!
