Office Christmas Party

  • Movie

Christmas is a time for family members to reunite around the fireplace. Or to stoke the flames of sibling rivalry at work. In Office Christmas Party, Jennifer Aniston and T.J. Miller play brother and sister who are both employed by a tech company; Aniston plays Carol, the interim CEO with a heart of coal, while Miller is Clay, the manchildish head of the Chicago branch who has a party trick up his sleeve when Carol tries to dismantle his office. How well do they get along? Well, this clip from the movie should help answer the question.

This week’s EW cover story takes you inside the raucous afterhours-workplace comedy (which hits theaters on Dec. 9) with a roundtable Q&A featuring Aniston, Miller, and costars Courtney B. Vance and Olivia Munn. Right here, we give you a preview of the Aniston-Miller rivalry.

ENTERTAINMENT WEEKLY: T.J., you drool on Jen and wrestle with her. How quickly did that sibling chemistry form? And what does it feel like to be inside of an Aniston headlock?

MILLER: It’s the softest, sweetest headlock a person being wrestled could ever hope to be in.

ANISTON: That’s a disappointment. I was hoping to be a mean, mean fighting machine like the Krav Maga student that I had been through months in training.

MILLER: When she slaps you, though, you know that she means it.

ANISTON: In my head, it was like a Jeanie-in-Ferris-Bueller-all-grown-up kind of relationship, where he was always getting away with murder, f—ing up royally, and Jeanie just couldn’t get a frickin’ break.

MILLER: We had brother-sister chemistry. [To Aniston] I was really surprised because I had heard about you and what a terror you were. [Aniston laughs.] I heard that you were very sweet, but I thought, “How do we establish this chemistry?” And so quickly you were welcoming and you were like, “Well, here, text me and let’s try to have a dinner.” [To EW] The chemistry was there already because she was a little sisterly to me on set, in a sense of “Hello, little baby wannabe-movie-star fellow, I’m going to look out for you.”

Aniston also remembers meeting Miller at an awards show. She describes it as very friendly and more than a little… wet.

ANISTON: I was a fan from Silicon Valley, so I knew of him. [to Miller] And I remember when you were hosting the Critics’ Choice Awards, like you were an insane human being taking on something like that.

MILLER: Wait ‘til you see this year.

ANISTON: It was incredible. I think we already knew we were doing it at that point. You came by after you had done this very committed bit on stage. [to EW] It was one of those “Hey!” “Hi! You’re doing amazing!” And then we were absolutely soaked down the back of our necks because of the amount of sweat that was pouring off him. He’s quite a shvitzer.

MILLER: Well, I was carrying a four-person puppet rig.

ANISTON: But I felt like we knew each other. In that one little moment I felt like, “He’s the sweetest guy.”
