The tour was chronicled in the documentary, Celine: Through the Eyes of the World, which gave the "unique opportunity to follow Celine everywhere, on stage, backstage, enjoying free time with her family; this movie will show it all."[40] It will be released on DVD and Blu-ray on May 4, 2010.
Taking Chances World Tour: The Concert is set for release also on May 4, 2010. It will contain a DVD and a live CD of the English and French setlists (each released separately). The English set list was recorded in Boston (on August 12 and 13, 2008), while the French one in Montreal (on August 31 and September 1, 2008). There will be also a deluxe edition including both DVDs and a 52 page booklet and fold-out souvenir postcards.
