If you’re watching and enjoying Showtime’s new Masters of Sex series (and you should be, on both counts), you might want to check out this 2004 movie, a biography of another pioneer in the field of scientific research about human sexuality. Liam Neeson stars as Prof. Alfred Kinsey, whose study of male sexual behavior was published in the 1940s, and caused a major scandal, predating the work of Masters & Johnson dramatized in Masters of Sex. Among the co-stars featured in Kinsey: Laura Linney, Peter Sarsgaard, John Lithgow, Tim Curry and Oliver Platt.
