The director of 'Love Actually' says the movie's lack of diversity makes him 'feel uncomfortable and a bit stupid'

• "Love Actually" director said the lack of diversity in the film makes him feel "a bit stupid." 
• "My film is bound, in some moments, to feel, you know, out of date," Richard Curtis said. 
• The film has faced scrutiny for featuring only heterosexual relationships and a mainly white cast.

"Love Actually" director Richard Curtis told Diane Sawyer that the lack of diversity in his iconic holiday-season film makes him uneasy. 

During an ABC special memorializing the film on its 20th anniversary, Sawyer asked Curtis if anything from "Love Actually" makes him "wince" in retrospect. 

"The lack of diversity makes me feel uncomfortable and a bit stupid," he responded. "I think there are three plots that have bosses and people who work for them."

The holiday romance follows a slew of characters and their romantic relationships through interweaving storylines. The characters are mainly white, and all the love stories feature heterosexual couples.

"There were things you'd change but thank god society is changing," Curtis told Sawyer. "So my film is bound, in some moments, to feel, you know, out of date."

The movie has faced scrutiny since its release, namely over the lack of diversity Curtis mentioned, yet it has remained popular over the years. 

When asked why she thinks it has remained relevant, CNN reported that star Emma Thompson said it's "Because I think that we forget, time and time again we forget, that love is all that matters."
