In S10/E12 "Go Make", Rebecca and Sam are still trying to have a baby together. Rebecca and Sam are at a fancy hotel, and Rebecca has a fantasy about coming home to Sam when he's kissing another woman. Right at the 16:10 mark (on Netflix at least) they show the other woman's face.

She has no lines, but she looks soooo familiar! Does anyone know who it is? Imdb was no help. It looks a bit like Sophie Marceau, but I'm not sure.

I tried to attach two screen captures of her, but in case they don't come through, here are the links:

No idea, sorry.

No idea, sorry.

Thanks for taking a look.

Hey, I think she appears two episodes later! (S10E14 "No Rest for the Woody") Here she is at 14:00 and 14:14:

Good eyes, everyone. Don't know who this actress is either, but it's interesting that she's in two episodes playing an uncredited?! role in each. I just saw S10 on DVD & do remember the fantasy scene - very funny. It reminded me of another "dream sequence"?! scene at the end of S05 showing what would have happened if Diane & Sam had gotten married.

There were plenty of attractive women on the show who didn't have any speaking parts; they were just seen in the background walking/sitting in the bar; in some cases you just saw them from the back - LOL.
