'William & Catherine: A Royal Romance' preview

Can't get enough of the fictionalized versions of the royal romance between Prince William and Catherine, Duchess of Cambridge? The Hallmark Channel has another version for you - "William & Catherine: A Royal Romance."

This newest Royal Wedding made-for-TV movie stars Victor Garber as Prince Charles, Jean Smart as Camilla, Lesley Harcourt as Diana, Princess of Wales and newcomers Alice St. Clair and Dan Amboyer as the titular characters.

St. Clair tells Zap2it that portraying Kate Middleton was "quite a challenge and relatively daunting, but at the same time, it's quite amazing to play someone so of-the-moment. I felt very privileged."

The "Royal Romance" movie premieres Saturday, Aug. 27 at 8 p.m. ET on the Hallmark Channel.
