Day 2: Cathy Munro
You never see her face, but Cathy Munro played two different characters in The Empire Strikes Back. Bounty Hunter Zuckuss and the short Wiorkettle in Cloud City (who you’ll probably only see in Empire merchandise).
I also found this interview with Cathy Munro from the Lexington Comic and Toy Convention Video in 2017.
