DR. SARA RETURNS TO 'PRISON BREAK' AND MORE FIRST LOOKS
Dr. Sara Tancredi is returning to the Fox drama Prison Break, and, muses actress Sarah Wayne Callies, ''she's very different.'' Sure, she has a head! After last year's decapitation, Tancredi reunites with Michael (Wentworth Miller) — see them snuggle in the Sept. 1 season 4 opener — but it's not all smooth sailing, says Callies. ''She's been to hell and back. There's a lot separating them.''
