Despite her presence in the film, however, she rarely speaks. She is mostly seen staring Frank in silence.
Considering the capability of 'The Piano' actor, some have questioned why a talented actress would be so underutilized, reported Variety.
The 76-year-old actor, however, has defended Scorsese and screenwriter Steven Zaillian's choice to minimize her words.
"She was very powerful and that's what it was," De Niro told USA Today. "Maybe in other scenes, there could've been some interaction between Frank and her possibly, but that's how it was done. She's terrific and it resonates."
Paquin herself defended the role and took to her twitter handle earlier this month, agreeing with a user who scoffed at the idea that Scorsese ordered Paquin to appear in the film.
"Nope, nobody was doing any 'ordering,'" she wrote. "I auditioned for the privilege of joining the incredible cast of 'The Irishman' and I'm incredibly proud to get to be a part of this film."
