For once, someone actually did go broke underestimating the intelligence of the American people. Duck Commander, a musical based on the Robertson family’s redneck poseur reality show, Duck Dynasty, opened at the Rio with a bang on April8…and closed with a whimper on May 17, playing to audiences that reportedly filled about 10 percent of the theater. The show had Broadway names in its pedigree and professional polish, but, well, how many people come to Las Vegas for entertainment that involves “faith and family?” Interestingly, Duck Commander shared its host casino with magician duo Penn & Teller. Penn Jillette is an outspoken atheist, while Robertson family patriarch Phil Robertson often speaks of various tragedies being God’s punishment. If Duck Commander got canceled while Penn & Teller were in their 14th year in Vegas and headed for a Broadway residency … well, perhaps ol’ Phil oughta rethink that divine judgment thing.
