Allison WilliamsEXCLUSIVE: Allison Williams, HBO Girls co-star and daughter of NBC Nightly News anchor Brian Williams, is in talks to play the title role in Rosaline, the Shawn Levy-produced feature based on Shakespeare that is mobilizing at 20th Century Fox. I’ve heard Williams is also on the short list for the Fantastic Four reboot, which is in the very early talking stage. Maybe not too long until Brian Williams is known as Allison’s dad. She’s repped by Paradigm. Rosaline is based on the Rebecca Serle book When You Were Mine.
