"There's a period of grief, a mourning process, and then perhaps we'll be able to consider, say for instance, you playing Samantha," Parker, who stars as Carrie Bradshaw in SATC, told DeGeneres on Wednesday's episode of The Ellen Show.
So what does Cattrall think of the casting choice?
"She'd be fabulous!" Cattrall tweeted Wednesday along with two thumbs up emojis.
A day later, Cattrall had a couple more suggestions as to who should play Samantha.
She told her Twitter followers, "I am partial to @TheEllenShow but @Oprah was always my 1st ❤️. But then there are the goddess's @TiffanyHaddish or @SofiaVergara So many fabulous actresses to choose from that will make Samantha their own!"
