Filming got under way today on a 'sequel' to Love Actually - a 10-minute skit for Comic Relief reuniting the characters from Richard Curtis' 2003 romantic comedy.
Liam Neeson and Thomas Brodie-Sangster - who played father and son Daniel and Sam - were the first to reconvene, filming on London's South Bank.
Emma Freud, director of Red Nose Day, shared some behind-the-scenes photos on Twitter:
Their co-stars Keira Knightley, Hugh Grant, Martine McCutcheon, Colin Firth, Bill Nighy and Andrew Lincoln and also expected to appear in the Comic Relief special, 'Red Nose Day Actually' will revisit the characters "to discover what they're up to in 2017".
Emma Thompson, who gave one of the most memorable performances in the original film, is not on the list of those returning. Kris Marshall, Laura Linney, Chiwetel Ejiofor and Martin Freeman are also missing from the line-up.
A spokesman said some original cast members were juggling prior work commitments. Alan Rickman, who played Thompson's husband, died last year.
The film will be shown as part of BBC One's Red Nose Day broadcast on Friday March 24.
Richard Curtis said: "Over the years I've enjoyed doing Red Nose Day specials of TV things I've worked on - Blackadder, The Vicar of Dibley and Mr Bean. It seemed like a fun idea this year to do a special sketch based one of my films, since Red Nose Day is now in both the UK and America.
"I would never have dreamt of writing a sequel to Love Actually, but I thought it might be fun to do 10 minutes to see what everyone is now up to.
"Who has aged best? - I guess that's the big question... or is it so obviously Liam?"
He added: "We've been delighted and grateful that so many of the cast are around and able to take part - and it'll certainly be a nostalgic moment getting back together and recreating their characters 14 years later. We hope to make something that'll be fun - very much in the spirit of the original film and of Red Nose Day - and which we hope will help bring lots of viewers and cash to the Red Nose Day shows."
