Something interesting I couldn't help but notice is how Sharon Tate became friends with two Peyton Place stars: Mia Farrow and Barbara Parkins. Yet, despite the latter two being former costars, I never heard about the three women ever interacting at once.
Mia only acts with people she´s adopted. And suits everybody else. Look what she had to say about Joannie Crawford, the nerve!

"As Escola shared their admiration for Crawford’s film
Our Dancing Daughters, the 80-year-old didn’t hold back. “She’s scary,” Farrow revealed. “And she was scary in person as well.”
(Look who´s talking!)

During her teenage years, while filming the TV version of
Peyton Place on the Fox lot in California, the actress described a strange encounter with Crawford.
At the time, the Academy Award winner – nearly four decades Farrow’s senior – was married to Alfred Steele, the then-president of Pepsi-Cola.
According to Farrow, she began behaving in ways that struck the young actress as deeply odd – leaving a lasting impression that clearly lingers to this day.
“For whatever reason, she started sending a whole refrigerator of Pepsi Cola for my trailer ’cause I was in a TV series called Peyton Place,” she explained.
“I don’t particularly like Pepsi Cola, but a lot of Pepsi Cola kept coming to my trailer, more than anyone would ever want,” Farrow added. “And then she came over to see me, and I got a strange vibe from her.”
So, PEPSI = SAPPHIC LOVE
Away from the set, Farrow also had a few weird moments with the legendary actress in New York at her mother, Maureen O'Sullivan’s, house.
“I hung up people’s coats for my mom when they came into the house. And I hung her coat and out falls a flask of alcohol,” she recalls. “She grabbed it like that, and she put it in her handbag. She drank quite a lot.”
Yes, but she smoked too!
Following that, 17-year-old Farrow was invited to Crawford’s apartment in the city. Thinking it was a party, she agreed to go. “But I arrived, and I was the only one there,” she told Escola.
Everything in the apartment was green, bathed in low, moody lighting. There were no other guests.
Again, PEPSI = SAPPHIC LOVE
Feeling extremely uncomfortable, young Farrow made up an on-the-spot excuse to leave. “I just made up a lie that I wasn’t feeling very well and I didn’t want to give her any diseases,” she shared. “I think I said the word ‘diseases’ as I walked out of the room. I was scared of Ms. Crawford.”
I think Michelle Phillips was part of their (Polanski´s) circle. She even talked about it on a video.

"Oh sure, little thing Mia thought she was the Queen of England!"
