The voices of actors Alfred Enoch and Bonnie Wright will be heard in the audiobook adaptation of Madly, Deeply: The Diaries of Alan Rickman, according to reports. Wright and Enoch both played Dean Thomas and Ginny Weasley in the Harry Potter movie series. Rima Horton, Rickman’s wife, and Steve Crossley, a close friend, will both provide their voices to the audiobook.
In all eight Harry Potter movies, Alan Rickman played Severus Snape, the enigmatic Potions Master at Hogwarts School of Witchcraft and Wizardry. His seeming hostility towards Harry (Daniel Radcliffe) and his pals contributed to the mystery surrounding his character’s past, which was increasingly unraveled as each year at Hogwarts went on.
