Debenhams Goes Long and Starry for Its 2026 Christmas Film

TL;DR: Debenhams has fired an early shot in the 2026 Christmas ad race with a long-form, celebrity-led film starring Emily Atack and Mathew Horne, built around the simple promise that online shopping with Debenhams is easy.
The festive advertising season now starts in October, and Debenhams has made sure it is not left behind. The reborn online retailer has unveiled a star-studded Christmas campaign well ahead of the big guns.
Starring Emily Atack and Gavin & Stacey's Mathew Horne, the film leans into two trends shaping this year's festive slate: long-form storytelling and famous faces.
A different kind of Debenhams
Since relaunching as a pure-play online brand under Boohoo ownership, Debenhams has had to rebuild awareness almost from scratch. A big, celebrity-fronted Christmas film is a statement that it intends to compete for festive attention, not just festive baskets.
The creative reminds shoppers how easy online ordering is — a sensible message for a brand whose entire proposition is now digital, and whose challenge is reminding lapsed department-store customers it still exists.
Why celebrities, why now
Famous faces are a shortcut to fame and recall, and at Christmas — when every brand is shouting — that shortcut matters. The risk is that celebrity can overshadow the brand if the link is weak.
Debenhams mitigates that by tying its talent to a clear, ownable message about ease and convenience, rather than borrowing fame for its own sake. The best celebrity ads make the star serve the story, not the other way round.
The early-bird festive strategy
Launching in mid-October buys share of voice before the John Lewis-era blockbusters land and before budgets everywhere get crowded. For a challenger, going early is often the cheapest way to be remembered.
The lesson for smaller retailers is the same: the businesses that plan and publish their festive message early capture intent while rivals are still finalising theirs.
