Susan Slade (1961) in which poor Stevens was a knocked-up seventeen year-old forced to watch her mother Dorothy McGuire raise the baby as her own rather than invite a scandal. Donahue played one of Stevens' suitors, wondering what it was that made her fret so over her baby "brother."
Parrish (1961), in which Donahue played the stepson of a tobacco magnate who romanced three young ladies, one of them being sharecropping Stevens. (This time out, Stevens was preggers again! And again it wasn't Donahue's.) Yes, this was their year and, in many ways it was all downhill from here.
Stefanie Powers while Stevens juggled Robert Conrad and Ty Hardin (though a gal could face bigger problems!) Within just a couple of years, the wattage faded from their stardom and, though they continued to work, it was never with the same fanfare they'd enjoyed in the early-1960s.
