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 hot spot 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 Adrian 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!
