In an inevitable but of fun casting, Dean Stockwell appeared opposite his Quantum Leap co-star Scott Bakula again when he played Colonel Grat in the Enterprise Season 1 episode "Detained."

Stockwell started acting professionally during the mid-1940s. He is perhaps best-known for playing Rear Admiral Albert "Al" Calavicci in the NBC series with Bakula, though his comic turn in Married to the Mob is one of his best-nown film roles.

More recently Stockwell had a recurring multiplicitous role in Ronald D. Moore's Battlestar Galactica as one of the seven known human-like Cylon models — often seen several times in a shot at once.
