Detroit challenging Dunkirk for this week's Number 1 DVD

Plus many of you are getting fit with Davina McCall this new year.

Period crime drama Detroit is the biggest competition to Dunkirk's dominance on the Official Video Chart this week.

Detroit, which stars John Boyega and Will Poulter, currently occupies the Number 2 slot on today's Official Chart Update, which tracks the first three days on this week's sales window. As it stands, Dunkirk will top the DVD and Blu-ray chart for a fourth week, and would become the longest-running chart topper since Rogue One spent four weeks at Number 1 in early 2017.

Another new entry, science fiction thriller Beyond Skyline is at Number 3, followed by Davina McCall's latest fitness DVD, Toned in 10, which rises 15 places to a midweek placing of Number 4. English-language French-Belgian war movie The Man With The Iron Heart is also selling well at Number 5.

New entries and high climbers

Two more new entries are expected to impact this week's Top 40, the next highest is Leatherface, the Texas Chainsaw Massacre prequel at Number 16, plus there's a high climber of nine places with The Crown: Season One at Number 29.

Finally, Geo-Disaster, an action movie that sees Los Angeles hit by a super volcano, a mega earthquake and a twister at the same time (crikey) is at Number 30.
