Does Actress Cynthia Stevenson Resemble Glenne Headly or Alan Cumming?

Home For The Holidays (1995) actress Cynthia Stevenson may resemble Glenne Headly & another actor, actress or group from some TV series or movie I was not quite sure of. I thought Eyes Wide Shut (1999) actor Alan Cumming may also resemble her. Headly & Cumming were in separate episodes on NBC TV sitcom Frasier (1993-2004). Headly played a guest caller in S2.E21 "An Affair to Forget" in 1995. Cumming guest starred in S10.E17 "Kenny on the Couch" in 2003.
Connections:
- Cynthia Stevenson & Glenne Headly were in separate episodes of the Monk (2002-2009) detective TV series on USA. Stevenson was in S5.E6 "Mr. Monk and the Class Reunion" in 2006. Glenne Headly was in S2.E5 "Mr. Monk and the Very, Very Old Man" in 2003.

I don't understand the point of the question. Why would any two bear any resemblance?
