Redford relieved at Sundance close

Utah - Founder Robert Redford is glad this year's Sundance Film Festival is coming to a close.

The 74-year-old actor says it's "always a relief" when the 10-day event wraps because "it's really exhausting".

He's happy, though, about the success of this year's festival, with about 45 films being sold up about 220% from 2010, when only 14 films were sold.

Redford believes the studios are taking an interest in the movies at Sundance because they're realising "there are audiences" for independent films.
