For Gwyneth Paltrow, the answer is easy: Shallow Hal, from 2001.
She once again expressed her distaste for the film on Netflix's "The BFF Test."
She quizzed her assitant, Kevin Keating, who correctly guessed that Shallow Hal is her least favourite movie role.
Gwyneth Paltrow's movie Shallow Hal (2001)
Paltrow starred alongside Jack Black in Shallow Hal in 2001. The film was directed by the Farrelly brothers, also known for films including Dumb & Dumber, Kingpin, and Me, Myself & Irene.
In Shallow Hal, Paltrow wears a "fatsuit." She meets Jack Black's character, who is hypnotized into seeing the inner beauty in women - which allows only him to see Paltrow's character in the actress's normally slender figure.
She looks back on the film as a "disaster."
Gwyneth Paltrow: Goop founder
Paltrow also criticized the film after its release in an interview with Variety.
"It was so sad; it was so disturbing. No one would make eye contact with me because I was obese. I was wearing this black shirt with big snowmen on it. For some reason, the … clothes they make for women that are overweight are horrible. I felt humiliated because people were really dismissive."
