One Day author leading writing team bringing one of the best-known literary creations of the 1980s to life

A writing team led by the One Day author, David Nicholls, and that includes Caitlin Moran is bringing Sue Townsend’s The Secret Diary of Adrian Mole Aged 13¾ to the small screen in a 10-part BBC One adaptation of the classic tale of teenage life in British suburbia.

Nicholls, who described the book as “a classic piece of comic writing and an incredible piece of ventriloquism on Sue Townsend’s part”, will adapt the book that produced one of the best-known literary creations of the 1980s.
