Sherry Stringfield, D.B. Woodside

ER vet Sherry Stringfield and 24 alum D.B. Woodside (former president Wayne Palmer) have joined the cast of Back, the CBS drama pilot starring Skeet Ulrich as a man who returns home to discover he was reported missing eight years earlier, after 9/11.

Stringfield will play Ulrich's wife, who in his "absence" has since moved on — with a new hubby. Woodside has been cast as a shrink whom Ulrich's confused character undoubtedly will need some time with.

In other CBS pilot castings, Katherine Moennig (The L Word's Shane) and Daniel Henney (X-Men Origins: Wolverine) have joined Three Rivers, the organ transplant drama starring Alex O'Loughlin, while Elisabeth Harnois (Bianca's first love on All My Children) will play a first-year resident on Miami Trauma.
