The actress – best known for her role as Narcissa Malfoy in the 'Harry Potter' movies – is the latest cast-member to join the Sam Mendes-directed James Bond movie, which has already begun filming.
Ola Rapace, Noomi Rapace's ex-husband, will also be appearing in the film, but neither of their roles are known.
Daniel Craig is reprising his role as the British spy, with Javier Bardem playing the lead bad guy.
Naomie Harris and Berenice Marlohe are taking on the Bond girl parts, while Dame Judi Dench will be reprising the character M.
Little is known about the storyline of the film, which experienced a number of delays because of problems at production company MGM, but it is believed to have been "scaled" back compared to normal standards.
A source said: "They've really scaled back. The lavish production and locations have been cut. There is only a reduced cast and crew travelling to the few overseas destinations. There won't be as much hand-to-hand fighting, it's gone back to blowing stuff up - including London's Vauxhall Bridge."
