Celebrities Who Have Secretly Written Massive Hollywood Scripts

The transition from acting to screenwriting is a common path in the film industry, yet many high-profile stars contribute to major scripts without the public’s immediate knowledge. While some actors are credited for their original screenplays, others operate as uncredited “script doctors” or use pseudonyms to ensure their work is judged on its own merits. These contributions often involve refining dialogue, restructuring plot points, or entirely overhauling characters for blockbuster franchises. Understanding the writing credits of these celebrities provides a deeper look into the collaborative and often hidden nature of Hollywood storytelling.

Her work included refining the dialogue and character beats for ‘Hook’, ‘Sister Act’, and ‘The Wedding Singer’. Studios frequently hired her to inject humor and sharp wit into scripts that were struggling during production. Although she rarely received official screenwriting credit, her influence is visible in many of the most successful films of the 1990s.

Wentworth Miller

The ‘Prison Break’ star surprised the industry when it was revealed he penned the psychological thriller ‘Stoker’. He used the pseudonym Ted Foulke to ensure the script would be evaluated by producers without any preconceived notions about his acting career. The screenplay was featured on the 2010 Black List, a compilation of the best unproduced scripts in Hollywood. Miller has stated that the writing process allowed him to explore a different creative side of the industry.
