Noomi Rapace "vomited" when she finished work on The Girl with the Dragon Tattoo series.
The actress splayed Lisbeth Salander in all three of the original Swedish movies - Dragon Tattoo and its follow-ups The Girl Who Played With Fire and The Girl Who Kicked the Hornet's Nest - and she was so tired by the time the final scene was shot, she could not drink the congratulatory champagne offered to her.
She said: "I'm done, I'm really finished with her. I did everything I could and I couldn't see any reason for doing it again.
"Why should I? You know, on the last day of filming the trilogy, the producers came with champagne - we'd been working on the films for a year and a half so they wanted to celebrate. I went to the loo and started to vomit. It was so weird. It was like I was trying to get her out of me."
The Swedish beauty admits she was "taken over" by the raw and gritty part.
She said: "I always try to put my characters as close to life as I possible can, but it's a high price because I know it will take over sometimes."
