LOS ANGELES, Nov. 17 (UPI) -- Katherine Heigl returns to the small screen on Monday four years after she left Grey's Anatomy to pursue a career in film, and the actress says she's "excited" to finally play an adult.
Heigl famously left ABC's medical drama because she was no longer happy with the material her character was given, asked how her new role as CIA agent Charleston "Charlie" Tucker is different from Grey's Izzy Stevens, the actress explained she played the two women at different times in their lives.
