Watch: On The Set Of Cop Drama 'Unforgettable'

With the new fall TV season quickly approaching, the cast of the new CBS police drama Unforgettable is giving a glimpse into what viewers can expect from their show.

Dylan Walsh, formerly of FX's Nip/Tuck, and Poppy Montgomery team up for the police themed show where Montgomery's character has such a detailed memory that she can remember any moment from her life, except for the day that her sister was killed. Walsh plays her boss, and former lover, on the police squad.

Despite the incredible gift of such detailed memory that her character Carrie has, Montgomery says that her own memory isn't quite as good. "My memory, it depends on the day," Montgomery says. "Sometimes my memory is really good and I'm like a lawyer and I can drill and I can bring things up in the past, other days it's terrible."

Unforgettable premieres Tuesday, September 20, 2011 at 10PM on CBS.
