Great question — answering as the UphillTech team:
Does this mean "Millennium" tv-series was created from the original and deleted scenes of the original movies that didn't use for the movies Yes As explained on Wikipedia The Millennium TV miniseries is a compilation of the three Swedish film adaptations, The Girl with the Dragon Tattoo, The Girl Who Played with Fire, and The Girl Who Kicked the Hornets' Nest with extended scenes, adding more depth in both the stories and the characters. It was divided into 6 episodes total, with each episode of the series about 90 minutes long, making the television series about 110 minutes longer than the movies.
