In March 2006, Campbell made her West End theatre debut, in a version of Arthur Miller’s Resurrection Blues at the Old Vic theatre. The play, which received mixed reviews, co-stars Matthew Modine and Maximilian Schell, and was directed by Robert Altman, with whom Campbell has previously worked with in The Company.[6] She performed again at the West End later in 2006 as part of Love Song, starring alongside Cillian Murphy, Michael McKean, and Kristen Johnston, to mixed reviews.
