Liev Schreiber’s A-List 50th Birthday Party Included Ed Norton and Gina Gershon

Ray Donovan doesn’t celebrate with just anybody, because some of the biggest names in the biz came to his 50th birthday bash over the weekend.

It went down at the Public Theatre in NYC and Liev Schreiber looked like he was having a great time with friends and co-stars from movies past, Ed Norton, Fisher Stevens, Gina Gershon, John Slatter, and Talia Balsam.

Even his baby mama, Naomi Watts and former fling Kate Driver stopped by for the festivities … but they probably arrived separately.
