• Keira Knightley said she hasn't watched "Love Actually" since attending the premiere in 2003.
• She said on "The Tonight Show starring Jimmy Fallon" that she doesn't like watching her own films.
• Instead, she said her favorite Christmas movie is "Die Hard."

"Love Actually" is one of the most successful Christmas movies ever, but Keira Knightley, who starred in it, hasn't seen the festive rom-com in years.

Knightley rose to fame after playing Juliet in the film, a character who discovers that her husband's best friend, the best man at their wedding, secretly loves her.

Knightley said on Monday's episode of "The Tonight Show starring Jimmy Fallon" that she hadn't seen "Love Actually" since attending the premiere at 18.

"This is nothing about 'Love Actually.' I don't really watch anything I do," Knightley said. "But I know that 'Love Actually' obviously has become this massive thing. And for lots of people, it's part of their Christmas."

Many actors, including Emma Stone, Adam Driver, and Meryl Streep, have said that they don't like or have avoided watching films they have starred in.

Knightley isn't even the only "Love Actually" actor who's avoided watching the movie again. Joanna Page, Knightley's costar in "Love Actually," also said on "Loose Women" in 2022 that she had only watched the film once.

According to The Metro, Page said it was "utterly traumatic" watching it at a film festival in Cardiff, Wales, with her then-boyfriend and her parents.

"Because I don't like watching myself at the best of times, and then also I don't particularly like watching myself naked on cinema screens," Page said. "So it was really, really weird."

When asked on "The Tonight Show " what her favorite Christmas film was, Knightley said "Die Hard," which led to laughter and applause from the crowd.

For years, fans have debated whether "Die Hard" should count as a Christmas movie because, as an action movie, it doesn't fit the mold of other films in that genre.

However, the film is set on Christmas Eve and features plenty of Christmas references.

Host Jimmy Fallon quickly changed the subject before a debate could start on the show.

Knightley was actually on the talk show to promote another project set in London during the Christmas season. Her new Netflix series, the spy thriller "Black Doves," premiered last week and landed Knightley a Golden Globe nomination.
