The now star-studded premiere of “The Lost Daughter” at the 2021 New York Film Festival marks the debut of Maggie Gyllenhaal’s directorial masterpiece. The psychological drama, a film adapted from Elena Ferrante’s novel, won critical acclaim for its raw depiction of motherhood and identity. It happened that Jake Gyllenhaal watched the premiere with his long-time girlfriend, Jeanne Cadieu-their first appearing together on the red carpet. Maggie’s husband, Peter Sarsgaard, and her sister added a family flavour to the occasion. The Gyllenhaal family is in close bond with each other, and as supporters of Maggie’s cinematic success, they celebrated the actress’s win.
