In 2014, Gazecki directed The Outrageous Sophie Tucker, showcased at the New York Jewish Film Festival. The New York Times reviewed it as not "especially well made", yet "because Tucker is such a gloriously rich figure...she renders its formal and aesthetic shortcomings (mostly) irrelevant".[11]The Hollywood Reporter called it a "loving documentary", yet having "its share of missteps".[12]
