The clip has been re-edited to feature footage from upcoming movie The Three Musketeers, starring Orlando Bloom, Milla Jovovich and James Corden.
'When We Were Young' is the second track to be lifted from Take That's recent Progressed EP, which topped the charts back in June.
The single received its official release on August 22 and will be used as The Three Musketeers' official theme song.
The Three Musketeers - starring Logan Lerman, Matthew Macfadyen and Ray Stevenson as the trio - will be released in the UK on October 14.
