she had previously taken up : "getting out of period gear and talking American, tries to broaden her range and is arguably well-cast". Knightley next played the titular character in Tony Scott's French-American action film Domino, based on the life of Domino Harvey. The film's release was delayed on several occasions and, on its eventual release in November, it received negative reviews and performed poorly at the box office.

The sequel instalments allowed Knightley to study sword-fighting, which she had sought to do since the first film. Filming for the projects took place in 2005; the Pirates of the Caribbean: Dead Man's Chest, released in July 2006. With the worldwide collections of $1.066 billion, it became the
