Nicholas Sparks Productions, which has been developing TV programmes and films based on the romance writer's works since 2012, is closing its doors, according to The Hollywood Reporter.

Under the banner, Sparks' novels Safe Haven and The Choice were adapted for the big screen, and last year (15), he collaborated with bosses at Warner Bros. TV to create a small screen adaptation of his bestseller The Notebook. However, executives at U.S. TV network CW decided to pass on the show in March (16), and a new version is being redeveloped for next year's (17) TV cycle. Sparks is expected to stay on as an executive producer.

Outside of his production company, 11 of his romance novels have been adapted into films, including 1999's Message in a Bottle, starring Kevin Costner, Robin Wright and Paul Newman. The film is Sparks' top earner, grossing over $118 million (£83 million) at the global box office.

He's also scored blockbusters with the adaptations of The Notebook, Dear John, and The Lucky One.
