Elijah Wood

Thousands of fans came out in New Zealand today to celebrate the world premiere of The Hobbit: An Unexpected Journey. Cate Blanchett was one of the stars that hit the red carpet, signing autographs and posing for photos on her way into the screening. Elijah Wood, Martin Freeman, Evangeline Lilly, and director Peter Jackson, who brought his daughter, also showed their support for the big event. Evangeline debuted a dramatic new look on the arm of costar James Nesbitt while Elijah waved to the overwhelming crowds as he emerged from the Hobbit house that was constructed at the front of the Embassy Theatre. It's just the beginning of press for the movie, which hits theaters on Dec. 14.

The cast of Celeste and Jesse Forever hit the Sundance Film Festival to show off their sweet movie on Friday. It's Rashida Jones's first screenplay, and she also stars alongside Andy Samberg in the project. On the red carpet at their premiere, the two gushed about working together, and Andy joked that if he was tasked with winning back an old love in real life, he'd probably revert to "d*ck in a box" tactics. Emma Roberts plays a pop star in Celeste and Jesse Forever and to get ready for the part she revealed that she channeled a little bit of Christina Aguilera in the "Dirrty" days, Britney Spears, and Ke$ha. We also chatted with Elijah Wood about his part in Celeste and Jesse and what it was like to see the The Hobbit trailer for the first time, which he said was "electrifying." Award season darling and The Descendants star Shaliene Woodley slipped in to see the movie, and later in the evening checked out Wiz Khalifa at the Bing Bar.

The first annual Critics' Choice Television Awards brought together some of TV's best this afternoon at the Beverly Hills Hotel. The shows that took home the biggest wins of the day were best drama series Mad Men and best comedy series Modern Family, but many individual actors were honored for their work as well. Busy Philipps embraced Elijah Wood, who presented her with her statuette for best supporting actress in a comedy, before giving an emotional speech on the podium. Sarah Michelle Gellar also took the stage to dole out an honor as she gears up for her own return to the small screen this Fall. She'll star in the new show The Ringer, which requires her to play dual roles as twin sisters on the CW. Lots of stars took advantage of the chance to catch up and pose for pictures backstage. Busy cracked jokes with The Office's B.J. Novak, Jon Hamm got silly with his best leading actor in a drama award, and Modern Family's Sarah Hyland said hello to Community's Danny Pudi. TV fans who want to see all of today's action unfold can tune into the Critics' Choice Television Awards this Wednesday night at 8 p.m., EDT, on the Reelz Channel.

Scarlett Johansson was all smiles last night at the The Art of Elysium Pieces of Heaven Art Auction, hosted by Vanity Fair in LA. She made a note of her bids among other celeb guests including Jesse Tyler Ferguson, Elijah Wood and Amber Heard. Odette Yustman attended with her husband Dave Annable, while Ginnifer Goodwin looked great in her LBD. David Arquette was also at the event hours before his post-rehab Oprah appearance aired, in which he revealed he had his first drink at the age of four, stole pot from his dad at the age of eight, and spoke about his intervention led by Courteney Cox and his sister Patricia. Anna Kendrick, Glee's Jayma Mays, and Justin Bartha were among the other charitable guests at the event.

Park City was bustling with celebrities this weekend as the 2011 Sundance Film Festival got underway. Buzz is on top of the latest news on what movies everyone is talking about and which are getting picked up, and we were hitting the party scene and scoping out what the stars were up to. The Bing bar was a huge hotspot with events from the My Idiot Brother bash to a late night Florence and the Machine concert, while the Variety lounge hosted their share of talent. Skullcandy and Express held nightly concerts at Harry O's, James Franco let loose at the Playboy event, and Adrien Grenier enjoyed a Chefdance meal. There was a lot going on and it's just the first couple of days, even Oprah is here! Robert Redford of course continues to oversee the whole show, which has provided another excellent group of premieres — stay tuned here and on PopSugar Rush for all our coverage from the festival!

James Franco was the man of the evening at Saturday's star-studded Art of Elysium Heaven Gala in LA. He posed with his Spirit of Elysium award and Kirsten Dunst, whom he credited with getting him involved with the organisation back when they worked together on Spider-Man 3. After hitting the red carpet, the stars enjoyed a cocktail hour with a Fatburger Truck, which Nicole Richie was particularly excited about. Jake Gyllenhaal didn't pose on his way into the AOE gala, but once inside he chatted with his friend and fellow godparent to Matilda Ledger, Busy Philipps. The celebrity attendees were treated to a Vogue fashion show featuring six designers and gorgeous hair done by Angus Mitchell Salon in Beverly Hills. Nicole, Rachel Bilson, Scott Caan, Elijah Wood, and more took the stage alongside the kids they work with, and everyone shared their experience working with the amazing organisation. Art of Elysium Heaven Gala is a fantastic event every year, and this one was no exception.

The Winter TCA is underway outside LA, and Tuesday night was Fox's turn to show off their talent and upcoming shows. The Golden Globe nominated cast of Glee attended the party, and Cory Monteith took a moment to chat with Buzz about his new Funny or Die video and working with Gwyneth Paltrow. Bones duo Emily Deschanel and David Boreanaz dropped in on the party, as did Hugh Laurie and Lisa Edelstein from the medical drama House. Cory's costars Chris Colfer and Matthew Morrison were back together yesterday morning to join Conan O'Brien and How I Met Your Mother's Jason Segel and Neil Patrick Harris for the Funny Men in TV panel. When asked about Glee airing right after this year's Super Bowl, Chris jokingly replied, "What's the Super Bowl?" For more details from the conference, make sure to stay tuned to Buzz!
