Richard Benjamin played Adam Quark, the captain.
Cyb and Patricia Barnstable (Who also were the DoubleMint twins, in the chewing gum commercials)
played Betty 1 and Betty 2, the co-pilots. One was a clone of the other, but neither would admit to it.
Richard Kelton played Ficus Pandorata, this ships Science officer, who was a humanoid plant.
Tim Thomerson played "Gene/Jene" who had both female and male personalities.
I will have pictures and links to a couple other Quark pages. I also have a mailing list just for Quark fans. The list is QuarkTV@Egroups.com.
