Jessica Chastain made her way to the NBCUniversal party, trophy in hand. Eerily, NBCU used a handful of rooms on the foutth floor as that party's bathrooms, all of which surrounded the former room 434, where Whitney Houston died in February. The room no longer has a number, and staff were actively using it during the party. It's now used for "storage," one security guard told me. (Photo by Katie Valentine)

"Django Unchained's" Christoph Waltz strikes a familiar pose.
After delivering an moving speech -- a highwater mark in the "lifetime achievement" variety -- Jodie Foster was ready to rock when she arrived at Weinstein. The actress is tailed by the nastiest security guard in the event business, who has been known to kick talent off of their own red carpets. Foster survived with plenty of Moet to spare.

Tina Fey and Amy Poehler's hush-hush afterparty at Soho House got rolling around 10:30 and went until late. (Here, they toast their co-host, Baileys). Aziz Ansari, Jon Hamm, Michelle Dockery, Seth Meyers, Kristen Wiig, Louis C.K. and more turned it into a dance party. Whitney Houston's "I Want to Dance with Somebody" went over as well as Fey and Poehler's monologue hours earlier. (Photo by Alexandra Wyman)

A an array of iPads at all events made security feel a lot tighter this year. Even Richard Gere was stopped as he approached Weinstein, with a guard telling him that he needed a wristband. After a beat, the guard pulled a band out of his pocket and banded Gere and wife Carey Lowell. (Photo by Ari Perilstein/Getty Images for TWC)

Guilt-free drinking: "Veep" star Julia Louis-Dreyfus receives a bottle of champagne before entering the Beverly Hilton, part of Moet's Toast for a Cause. Every glass raised earned $1,000 for a nominee's charity of choice.
"Boardwalk Empire's" Steve Buscemi, booze in hand, makes his way into the party.
Just after her Baltimore Ravens won the epic playoff game against the Broncos, Stacy Keibler was in good spirits for the Art of Elysium bash on Saturday night.

Before Globes Weekend, Chris Colfer premiered "Struck by Lightning." "While I'm sitting there acting, I'm wondering if everyone is judging my performance and the writing that I am spitting out as well," Colfer said of his writing-acting debut. Colfer's "Glee" pals Darren Criss and Harry Shum joined him at the L.A. premiere on Jan. 6.
"Struck by Lighning" star Sarah Hyland at Tribeca Films' afterparty at Eden.
Star Allie Grant (with producer David Permut), had worked with "Struck by Lightning" director Brian Dannelly before and knew she wanted in. Rebel Wilson was cast the night before shooting started. "Nobody had any idea (Chris) could write," Permut told TheWrap in November 2011.
And the winner is...Weinstein. The "must-attend" party had head-turning pairings, Robert Pattinson with his own tent, Kobe Byrant and a "Best Picture" photo booth with a sorceror's lens that made everyone's complexion look like Dita Von Teese. (No this was not written by Stefan from "SNL".) The night ended with Jon Hamm in the middle of a dance circle at Soho House with Michelle Dockery, Seth Meyers and Kristen Wiig. Photos of famous faces letting loose lie ahead.
