Beverly D’Angelo in First Love (1977)

She made her nude debut (of sorts) the previous year in an unlikely place – a broadcast network mini-series! Her areola was barely perceptible for a frame or two in Captains and the Kings – but it was clearly there (see below). The first three episodes of that series represented not only her nude debut, but her film/TV acting debut as well.
Time slips away from us, as marked by the fact that Bev, an early crush for some of us, is now 70 years old, although I think she looks younger.
