How I picture Theo
Marcello Mastroianni unfortunately deceased now, but I remember seeing him in Used People with Shirley Maclaine. This is how I have Theo pictured in my mind.
I loved him so much in Pret-a-Porter (and in a few Italian films I have seen)! Just imagine he has a tash (and unimagine Sophia - though I have no idea how one does that):
