As the Sundance Film Festival kicked off this weekend, the Hub at Park City Live, produced by Mirrored Media, got the buzz along Main Street.

Chelsea Handler, Charlize Theron and Mary McCormack stepped out of the snow Saturday and into the Hub after leading the Women’s March on Main Street. The trio of actresses became the face of the movement in Park City, taking the conversation beyond the march and into the Marie Claire Studio and 4K Ultra HD Showcase. Handler, Theron and McCormack spent quite some time at the lounge presented by the Consumer Technology Association, talking about human rights and how people can push for change by calling their senators every day to demand attention for their initiatives.

Other members of Hollywood's elite dropped in and out of the Hub to escape the snowy bustle on Main Street and speak further about this weekend’s current news topics. Aisha Tyler was spotted at the Hub sipping Tanqueray No. 10 Gin & Juice cocktails after talking to friends about the excitement from the march down Main Street.

"Band Aid" actress Zoe Lister-Jones was also talking about other popular political issues as she was seen at the Cool Effects booth discussing the importance of raising awareness for climate change.

"Big Bang Theory" actress, Kate Micucci checked out the new 4K Ultra HD Showcase presented by the Consumer Technology Association and was overheard explaining to friends the drastic image and motion quality improvement in videos that are not shot in 4K. Teresa Palmer and co-star Max Riemelt spoke about their newest movie, "Berlin Syndrome," at the Marie Claire Studio Saturday afternoon.
