How do you know they’re not identical? Wikipedia seems to think they’re identical.
The Olsen twins have made several movies together, and are non-identical.
More celebs with twins:
Mario Andretti
Jerry Falwell
Jerry Hall
Billy Dee Williams
Science-fiction author and physicist Gregory Benford is an identical twin.
To clarify: both Renee and Lucy Lawless played multiple roles on Xena, though none were explicitly twins.
However, in the same show Ted Raimi played not only Joxer, but also Joxer’s triplet brothers Jett and Jace. I assume that counts for the OP’s criteria.
Bruce Campbell played Good Ash and Bad Ash in Army of Darkness (and an army of mini-Ashes, too).
Good? Bad?
And for Og’s sake don’t mention this episode.
Sorry twickster :o
