The Host. Casting by Chels

• Melanie Stryder: Sophia Bush. Melanie needs to have dark hair with a tan athletic body. I think Sophia fits.

• The Voice of Wanda: Jennifer Connelly. Wanda's voice needs to be an older woman's voice, but not decrepit. I think Jennifer's voice can sound wise, but youthful.

• Jared Howe: Tatum Channing. Jared needs to be muscular and hardened, but have a hidden soft side. I think Tatum can do this.
  

• Ian O'Shea: Jared Padalacki. Ian is softer than Jared in my mind, but still muscular. This guys works. I might find someone better.

• Pet: Anna Sophia Robb. So Pet has to look like she fits with Ian. I think she needs to have a serious side to her, but also look like she giggles easily.
  

• Kyle O'Shea: Tom Welling. Ian looks just like Ian only bigger and taller. I think Tom looks like he could be Mr. P's older brother. It works.

• Sunny: Emmy Rossum. I feel like Sunny's host, Jody?, could have been more serious, like a bookworm, but Sunny brings out the doe-in-the-headlights feel while still looking cute.
  

• Jeb: Donald Sutherland. Jeb has to have a sense of humor and have some old-man muscles. I think Mr. Sutherland could be harsh or kind and joking at the drop of a hat, so I think he would be good in this role.

• Seeker: Alexis Dziena. The Seeker has to be short, wiry and full of fire. In the roles I've seen Alexis play I think she could pull this off.
