LOL. I had to explain it to some fans over here so I did a research on the character Suzanne in 
Tootsie. Turned out that the actress who played Suzanne was mis-credited. Her name is Suzanne von Schaack. On the credits of 
Tootsie at 
IMDb, she is credited as "party girl". :lol: You can see a photo of Suzanne von Schaack 
over here. If you have watched 
Tootsie, you'd know this was the one who played the girl named Suzanne at the party in 
Tootsie.
I don't see 
Peacemaker on Marg's filmography at IMDb, either. lol her role in it wasn't that small, and she actually had some lines. :lol: Plus other mistakes I have seen on that site, I'd say it is indeed a good resource for information about movies, TV shows and actors, but not everything over there is accurate.
I wish I could watch 
Thirtysomething again just to see Marg. This is one of my all-time favorite shows. It was on about the same time as 
China Beach. TV shows back then were great. Not so many special effects and technology, but great in other ways.
