Casey Affleck was just one of the Hollywood stars who walked away with an award at Sunday night’s 74th Golden Globes. Ben Affleck’s younger brother took home the accolade for best performance by an actor in a motion picture, drama for his role in “Manchester by the Sea,” and he acknowledged his family while accepting the statue. 

During his acceptance speech, the 41-year-old thanked his two sons, Indiana, 12, and Atticus, 8, for their support. “I just want to say that despite how I might think I’m in charge in my house, it’s my kids who give me permission to do this because they have the character to keep at bay all the noise that sometimes surrounds people who live publicly and to let me travel for months at a time,” he said. “I love you Indiana and Atticus.”

Affleck also gave a warm shout out to his estranged wife, Summer Phoenix. In March 2016, Affleck and Phoenix announced in a joint statement that they were separating after 10 years of marriage. “And to their mom who gave me every good acting idea I’ve ever had — thank you, I love you,” Affleck said during his acceptance speech.  

So who is Affleck’s estranged spouse? It turns out that like Affleck, Phoenix is also in the acting business. The 38-year-old has appeared on TV shows such as “Murder, She Wrote,” “Growing Pains,” “The New Leave It To Beaver” and “ER.” Phoenix has also starred on movies like “Suzie Gold,” “The Faculty,” “I Woke Up Early the Day I Died” and “Two for One.”

If the actress’ last name sounds familiar, that’s because she’s related to several famous Hollywood stars. Her older siblings are Joaquin Phoenix, Rain Phoenix, Liberty Phoenix and the late River Phoenix. In fact, Joaquin introduced her to Affleck in 1995 while he was working with Affleck on the film “To Die For.”

In addition to having several movies and TV shows under her belt, Phoenix is also a musician and was once in the band The Causey Way with sister Rain. Phoenix also lent her vocals to The Papercane’s album, a band Rain was in.

Throughout her career, Affleck’s estranged wife advocated for animal’s rights and became an activist for PETA. Affleck also shares that passion for animal activism with Phoenix.
