Enter the creative process of Ohad Naharin, an Israeli choreographer whose joyous performances have redefined the language of dance. Once a sought-after dancer in the company of Martha Graham, Naharin has spent the past 25 years pushing the boundaries of physical and political expression at Tel Aviv’s Batsheva Dance Company. Through rich archival footage, intimate rehearsals and eye-popping dance sequences, director Tomer Heymann crafts an affectionate portrait of a cultural maverick and his audacious efforts to bring the joy of movement to people of all ages and physical abilities. The product of an eight-year collaboration between Heymann and his subject, Mr. Gaga is a feast for the senses, celebrating an artist whose exuberant dances capture the thrills and burdens of having a body.
