'Girls Like Us' Casting: Allison Williams, Jessica Pare Read For Roles

Allison Williams could be going from "Girls" to "Girls Like Us." According to Variety, "Girls Like Us," based on Sheila Weller's book, is picking up steam with starlets testing for the roles of Carly Simon and Carole King.

Variety reports Williams, Analeigh Tipton and "Mad Men's" Jessica Pare are reading for the role of Simon. Meanwhile, "The Newsroom" actress Alison Pill, Olivia Thirlby, "For a Good Time Call's" Ari Graynor and "Ruby Sparks" star Zoe Kazan are reading for King.

Taylor Swift is in line to play Joni Mitchell.

The drama follows the careers and cultural impact of Mitchell, King and Simon. Katie Jacobs, a former "House" executive producer, is attached to direct with a script from John Sayles.

In an interview with author Caroline Leavitt from May 2011, Weller said she envisioned Swift as Mitchell. Weller also said she thinks Michelle Williams would be a good fit for King. "She has a gravity, a solemnity, which was an ineffable part of Carole's resonance and appeal," she said.

"Girls Like Us" still technically has not been given the green light.
