The "Love Actually" sequel short film won't feature Emma Thompson or a tribute to late actor Alan Rickman, who played Thompson's husband in the beloved 2003 romantic comedy.
Writer and director Richard Curtis told the Press Association that Thompson turned down a part in the Red Nose Day special because "she just can't do it."
When asked about about a potential tribute to Rickman, Curtis said, "You know dealing with Alan is very complicated so not really. We're not doing everyone. We're doing about two thirds of people."
The short film will feature many of the original key cast members including Liam Neeson, Keira Knightley, Hugh Grant, Thomas Brodie-Sangster, Andrew Lincoln, Martine McCutcheon, Colin Firth, Bill Nighy, Lucia Moniz, Olivia Olson, Rowan Atkinson and Marcus Brigstocke.
The 10-minute short film will be broadcast on BBC One on March 24 as part of the Red Nose Day telecast in support of Comic Relief.
