I also read that Carrie went to Norway because she wanted to be with Harrison and her mother wasn't very pleased with that. And besides, according to Rinzler's "Making of TESB" all 3 principals (Fisher included) arrived at London on Febr. 17 of 1979, with Fisher and Hamill flying to Oslo on Febr. 28. The public reason Fisher claimed at the press-conference was that she wanted to feel the atmosphere of the set. No mention of Sweden. And they had never planned any scenes with Carrie to be shot in Finse.
