An online casting call went out on Facebook on July 24, offering anybody the chance to co-star alongside actors Mary ElizabethWinstead and Topher Grace.
So on a Tuesday in July my wife, Elizabeth, and I join Henningsen, fishing guide Aaron Wert, cook Chad Winstead, wrangler Stacie Potts and four other guests at the Specimen Creek Trailhead, 10 miles south of Big Sky.
