Armie Hammer, Max Minghella and Rooney Mara have joined the cast of David Fincher’s “The Social Network” for Sony Pictures says The Playlist.

Dakota Johnson, Brenda Song and Josh Pence have also joined the $40 million Aaron Sorkin-penned project which deals with the founding of Facebook and the three key players behind it.

Hammer will play the Winklevoss twins. Shooting kicked off this week in Cambridge.
