Glynn made the move to features as the widow of a murdered CIA agent in Sydney Pollack's "Three Days of the Condor" (1976) and went on to appear as one of Ellen Burstyn's friends in "Resurrection" (1980). She was delightful as the pressed mother of Molly Ringwald in "Sixteen Candles" (1984) and offered a strong turn as the hateful daughter-in-law of Geraldine Page in "The Trip to Bountiful" (1986), directed by Masterson. The husband and wife duo have also collaborated as director and actor on "Blood Red" (1988), "Night Games" (1989) and "Convicts" (1991). Additionally, Glynn and Masterson played the on screen parents of their real-life daughter Mary Stuart Masterson in Francis Ford Coppola's "Gardens of Stone" (1987).
