Despite all her previous accolades, the first-time Oscar nominee -- who’s up for best supporting actress for her role in "Lady Bird" -- said she never imagined she’d be recognized by the Academy in this way.
"Just to be in the room is incredible," Metcalf, 62, told ABC Radio. "I just hadn’t planned on it ever happening to me."
"That’s been wonderful to have mothers and daughters come up and say they've seen the movie together and they've had an epiphany throughout it, you know, seeing each other through different eyes," she said.
The movie also resonated in Metcalf's own household when she watched the film with her teenage daughter.
"My older daughter and I had the side-eye glances at each other throughout the movie because she's heard me say and she has said [things], if not verbatim, but very close to some of the lines that are in the movie," she said with a laugh.
"Lady Bird" scored five Oscar nominations in total, including best picture, best actress for Saoirse Ronan and best director for Greta Gerwig.
Metcalf will back on the small screen when "Roseanne" returns to ABC on March 27.
The 90th Annual Academy Awards airs live on ABC Sunday night starting at 8 p.m. ET.
