The former footballer has a cameo in the upcoming movie, directed by his close friend Guy Ritchie. Details of his character have been kept under wraps, but some reports have said David's role helps kickstart all the action.
Guy hinted in a recent interview that David would be somewhat disguised but viewers should still know it was him. Guy told Access Hollywood: "He's marginally disguised but he's in the movie. I mean, once you know who it is, you'll know who it is."
Now, Becks has shared an image to Instagram that appears to have been taken on the movie set. In it, he's dressed in a suit and wearing thick rimmed glasses… but yep, we still know that's our Beckham!
David shared the photo in a post congratulating Guy on his marriage to Jacqui Ainsley on Thursday (and also to encourage fans to check out The Man From U.N.C.L.E. in cinemas).
He wrote: What a beautiful day today is going to be... I want to wish my mate and his beautiful bride an amazing day where friends and family come together to celebrate what they have and are going to create together over the years to come... Have an amazing day you two... Oh and by the way don't miss Man from U.N.C.L.E .. Proud to have played a small part
The movie arrives in cinemas on 14 August.
