We are continually told that Sundance is for the filmmakers. True enough, but at Dolly’s Bookstore on Main Street it is also for the authors. Right next to the Rocky Mountain Chocolate Factory – in case reading makes you hungry – Dolly’s takes advantage of the film festival by stocking up on film books and roping in authors for signings and readings. In recent years, producer Christine Vachon A Killer’s Life, Roger Ebert and others have showed up with their books. Manager Sue Fassett sets out to find literary connections the minute the Festival issued their line up.
