As previously reported, Red Nose Day Actually was announced back in February, when the stars of the movie filmed the 10-minute short. What you're seeing is some of the best talent in the animal business and, although I'm never one for nepotism, my own dog got on the team sheet.
Emma Freud, director of Red Nose Day and Richard Curtis's wife, posted images from the filming on Twitter.
The trailer is a nod to the "cue cards" scene from the film that has now become iconic.
The peacock network released a trailer for the short film, which will be part of their Red Nose Day special.
Is it really Liam Neeson and "definitely not Colin Firth"?
Comic Relief supporters in Swindon can accessorise their red nose with comedy waving hand glasses. That includes Keira Knightley, Chiwetel Ejiofor, Hugh Grant, Liam Neeson, Thomas Brodie-Sangster, Andrew Lincoln, Colin Firth, Rowan Atkinson, Martine McCutcheon, Lucia Moniz, Olivia Olson and Marcus Brigstocke.
The romantic comedy, set just before Christmas, has become a holiday staple, and so it's something of an event that members of the famous cast are reuniting in honor of "Red Nose Day", an worldwide charity campaign that raises money to combat childhood poverty.
She added: "Comic Relief T-shirts help raise so much money for good causes at home and overseas; however, we wanted to highlight the poor animal health and welfare being perpetuated by the use of Albert on its merchandise". BBC's Red Nose Day special will air Friday, March 24.
