Sandra Will Carradine has been active for a number of years with the Telluride Film Festival. In 1991, she left California and founded the "Sheridan Arts Foundation" to save and restore the historic Sheridan Opera House in Telluride, Colorado. The foundation raises tens of thousands of dollars each year with help from Carradine's Hollywood celebrity friends.
On April 1, 1994, she was involved in a Telluride heli-skiing company helicopter crash along with son Cade, Colorado real estate mogul Ricky Taubman, and supermodel/actress Christie Brinkley. Only Taubman sustained serious injuries.
