Mitchell was born Dominic Salvatore Miceli in Farrell, Pennsylvania. In 1951, he teamed with comic Sammy Petrillo for a nightclub act. Mitchell's cabaret-style crooning and Petrillo's manic, rubber-faced clowning bore more than a passing resemblance to the popular team of Martin and Lewis, which led to Lewis taking legal action. The suit was later dismissed. Movie producerJack Broder intended to star Mitchell and Petrillo in a feature-length comedy. Petrillo later recalled his suspicion that Broder never really intended to make the film: Broder expected Paramount Pictures to pay him off, but when Paramount dropped the lawsuit, Broder had to follow through. The resulting film was Bela Lugosi Meets a Brooklyn Gorilla, a jungle-themed comedy. Mitchell had a small appearance in the Martin and Lewis film Sailor Beware. After Mitchell and Petrillo parted ways, Mitchell stayed in show business, performing at nightclubs in New York, Las Vegas, Seattle, Palm Springs, Chicago, and The Cloisters, Crescendo and Coconut Grove in Los Angeles and began directing self-financed independent films such as Massacre Mafia Style and Gone with the Pope, which have since developed a cult following. In 1960, Mitchell provided the singing voice of Fred Flintstone for his friends William Hanna and Joseph Barbera on The Flintstones episodes "Hot Lips Hannigan" and "Girls' Night Out". Duke was a regular on the scene in Palm Springs, California, where he started the fad and trend of "Sunday Brunches" with shows including Liza Minnelli, David Janssen, Cary Grant, Frank Sinatra, and his son, guitarist/songwriter Jeffrey Mitchell, who got his start at the Ranch Club brunches with his father, Doug McClure, James Drury, and a myriad of stars including Lucille Ball, Red Skelton, Vince Edwards, and acts from the world of show-biz. Stars would take the weekend plunge into the Palm Springs scene and join the brunch festivities on Sunday. Several of Mitchell’s projects originally weren't released, including his "Tribute to Durante" and his second feature filmGone with the Pope, which only existed as a work print when it was found in Duke's son Jeffrey Mitchell's garage by Grindhouse Releasing’s Bob Murawski and Sage Stallone. Sage wanted to purchase Gone with the Pope from Jeffrey Mitchell and he did, save for the musical rights, as Mitchell's music is published out of London. It was carefully restored and released theatrically in 2011 by Grindhouse Releasing, which has also restored and released Mitchell’s Massacre Mafia Style, owned by Jeffrey Mitchell and Bob Murawski, on Blu-ray in 2015.
