Sarah Michelle Gellar nearly fell asleep during her sex scene in Southland Tales.
The 30-year-old actress – who plays a porn star in the new film – struggled to stay awake for the raunchy sequence because she had just eaten a huge Thanksgiving turkey dinner.
She said: “I filmed a love scene on Thanksgiving and I had eaten all this turkey and mashed potatoes. I was like, ‘I seriously have to film a sex scene right now?’ I was so tired from all the tryptophan – an amino acid in turkey that makes you sleepy – that I just wanted to sleep!”
Gellar also claims she knew she had made it as an actress when she saw a porn spin-off of her hit US TV show Buffy the Vampire Slayer.
She added to Maxim magazine: “I think there was a Muffy the Vampire Layer. We had a cast viewing in one of the trailers. You know you’ve made it when they make a porn version of you!”
