JK Rowling is to attend a special screening of Harry Potter spin-off movie Fantastic Beasts And Where to Find Them.
The screening will take place at Carnegie Hall in New York in November.
It is in aid of the Lumos Foundation USA, which works to keep disadvantaged children with their families and out of institutions worldwide.
Potter author JK will attend, as will Oscar-winner Eddie Redmayne, who stars as Newt Scamander in the film.
Other cast members are also expected to be there.
The film takes place within the Harry Potter universe, but is set in New York several decades before the boy wizard is even born.
