It's Kelly Macdonald as Carla Jean Moss from No Country for Old Men. I made the icon after I wrote that John Winchester/Carla Jean piece and I just love her in general. I've never seen Macdonald play a character I didn't enjoy and I will watch a movie just because she's in it!

It's possible Gandhi has an actor/director/theme in common with Fido, but I'm not sure which!
