The Blue Valentine star landed a Best Supporting Actress Academy Award nomination for her role in the hard-hitting drama, but she explains she hasn't seen the movie because she's convinced she won't be able to control her emotions.

"I've seen some scenes from the movie," she tells TheWrap.com, "but I haven't actually watched the movie. My friend and I were going to see it at a theatre in Brooklyn, but I got called into work."

Kenneth Lonergan's film, which also stars Casey Affleck, has garnered a string of top awards nominations and critical acclaim, and the actress admits she didn't know Manchester by the Sea would receive so much praise when she began working on the movie.

"Not a clue, not an idea," she adds. "It was just another barely held-together independent film production. We were cold and hungry and tired. But we believed in Kenny (Lonergan)."

And she credits the director's script, which has also landed Kenneth an Academy Award nomination for Best Original Screenplay, for helping her get into character as Randi Chandler.

"With a script like this you can really lean into it," she said. "You can feed off of it."

Michelle has been nominated for three Oscars in the past and won a Golden Globe for her portrayal of screen icon Marilyn Monroe in My Week with Marilyn in 2012. Her co-stars Affleck and Lucas Hedges have also been Oscar nominated for Best Actor and Best Supporting Actor, respectively.

Lonergan's film chronicles the story of an uncle, who is asked to take care of his teenage nephew after the boy's father dies.
