Class of '92 stars David Beckham, Paul Scholes, Nicky Butt, Ryan Giggs and Phil and Gary Neville arrived at the documentary's premiere at Leicester Square.
The former England captain attended the event with wife Victoria, and the couple's three sons Brooklyn, Romeo and Cruz.
When asked about reports that Beckham could become Sir David in the New Year Honours List, Styles replied: "Why not? He's a national treasure isn't he? It makes sense. I thought he was already."
Victoria Beckham said she had "so much fun" guest editing Vogue Paris' Christmas issue and gave her Twitter followers a sneak peek at the two front covers.
Vogue says the issue "transports readers straight into the world of Victoria Beckham" with the help of an interview, anecdotes, family photos and even some drawings by her children.
The front covers both feature Victoria and David Beckham and were shot by photographers Inez and Vinoodh.
Vogue Paris described the Spice Girl-turned-designer as "a fashion superstar on the New York scene", adding, "She's built a global business empire, never failing to build on her success wherever life has taken her".

David and I are supporting the Red Cross Shop Drop for the Philippines campaign and we urge everyone in Britain to do the same.
Everyone has something in their closet they were holding onto, a dress, suit, or pair of shoes they thought they might wear again.
Dig them out, bag them up, drop them off and give someone else the chance to buy them, raising much needed funds for the Red Cross aid effort.
