An enigmatic producer of features since the 1970s, Greenhut has carved out a significant place in the American film industry without often leaving his native NYC. After studying at the University of Miami as a music major (with "a minor in the horses"), Greenhut graduated to films as a production assistant on Arthur Hiller's 1967 comedy "The Tiger Makes Out". He worked in various production capacities over the next seven years, rising through the ranks to become a production manager, assistant director and associate producer. Greenhut served in that last capacity on "The Front" (1976), a Hollywood blacklist drama starring Woody Allen and made a career transforming connection. He next surfaced as the executive producer (as well as production manager) of Allen's "Annie Hall" (1977). Greenhut went on to produce or executive produce every Allen-directed film through the period musical comedy "Everyone Says I Love You" (1996). The two diehard New Yorkers enjoyed a long and enviable collaboration.
