Dish served best cold. Lookalikes on same show.

Deniece Nichols and Karen Black on the same show. I always thought they resembled each other. Of course Heat had Pacino and DeNiro. Double Take had a couple of Bruthas. Departed had Wahlberg, DiCaprio and Damon in a trifecta of young, stocky, cool whiteboy types who don't look totally dissimilar. Any other examples where non-related actors are obviously on the same set at the same time who resemble one another?
