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 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.
