Star Trek: 10 Things You Didn't Know About Weyoun

10. Seeing Double

Combs appearance in Dogs of War as both Weyoun and Brunt is not as unique as fans may appreciate.

In fact it wasn't the first or second time that an actor would appear in two different roles in the same episode.

Track back to season three of TNG and The Defector. Patrick Stewart would act as both Captain Picard and also as (uncredited) Michael Williams in the holodeck recreation of Shakepeare's Henry V.  The other would be Brian Markinson. 

Markinson would appear alongside Jeffrey Combs in season five's In the Cards as Doctor Giger but over on Voyager he would take on the role of Lieutenant Pete Durst in Cathexis and Faces. In the second of those episodes he would also play the part of Vidiian Sulan who grafts Durst's face onto his own. Naturally it would make sense to have Markinson play both parts!

Let us not forget the Next Generation episode Brothers, in which Brent Spiner plays Data, and Lore, and Noonian Soong!

What does make Combs unique in this realm is that, thanks to his appearance as a patron of Vic Fontaine's club in What You Leave Behind, he is the only actor to have appeared in two different roles (credited or uncredited) in two successive episodes. Combs is also the only actor to have his name with both characters listed in the show's opening credits.
