Is it just me or does anyone else notice when watching the back of her head how thin her neck is compared to Patty's? I find it a little distracting that they didn't choose someone who's body structure was more similiar. Rita had this long, swan-like neck and very narrow shoulders compared to Patty.

I guess I am going to look closer, because I've never noticed before.

OMG I've noticed this too especially when Patty/Cathy had the shorter hairdos in season 2. Pat's neck was a bit thicker and her shoulders were broad compared to Rita.

I have been watching S2 the last month so that's probably why I noticed.

There was another stand-in I think on the Patty Duke Show. The mysterious "Diane" that Patty mentions in an interview.

TV edit error - somewhat !

Here's a picture I took off my TV of the girl that was know on the set as "the back of Patty's Head" - she did a few interviews I read years ago
