Anyone for a round of "who the heck am I thinking of"

[RumNotRun]

I'm trying to remember the name of an actress who always plays a kind of snobby/WASP type woman. She has long blonde very straight hair. Her nose is quite distinctive, very thin but it always makes me thinking of a botched nose job cause (I think) the nostrils are quite pinched. I think she's in light comedy films, like Four Weddings or Three Men. Never a lead actress and it's not Holland Taylor, Jennifer Coolidge, or Christine Baranski.

Diane Keaton and Sissy Spacek are character actresses in light comedies

Lisa Kudrow?

Edie Falco?

Harriet Walter?

Leslie Mann?

Judy Greer?

Kristen Scott Thomas

Emily blunt

Or Glenne Headley? (Sadly no longer with us).

Joely Richardson.

Is she British?

Anna Chancellor?

Lily Rabe?

This

British or American?

Michelle Pfeiffer (from the physical description)?

None of those so far, but thank you. I THINK she's posh American, but I can imagine her being in a Hugh Grant film so she may well be a posh English woman (or at least play one). She's not as famous as most of the people mentioned, but is an older actress now.

Tilda Swinton?

Penelope Keith?

Nicola Sturgeon

Kelly Rowan or Kelly Rutherford

The wonderful Gina McKee?

Julia Duffy or Morgan Fairchild

(I have never heard of them but on googling, they match your description)

Another vote for Gina McKee (who is great!)!
