United Kingdom, Jan. 25 -- Olivia Wilde thinks sex scenes haven't been "particularly realistic" for a long time.

The 41-year-old actress has claimed that Gen Z wants to see less sex in movies, observing that X-rated film scenes are often unrealistic.

"Therefore, there's been this movement now towards authenticity, which is really good. So I choose to interpret that statistic maybe as Gen Z saying, 'We don't want to see inauthenticity anymore.
