Actor Jonah Hill will no longer promote any of his films.
The Superbad star has experienced anxiety attacks for nearly 20 years, which are "exacerbated by media appearances and public facing events", so after completing work on Stutz, a documentary film about mental health, he is stepping away from promoting his projects.
In an open letter, he wrote: "I have finished directing my second film, a documentary about me and my therapist which explores mental health in general, called Stutz.
"The whole purpose of making this film is to give therapy and the tools I've learned in therapy to a wide audience for private use through an entertaining film.
"Through this journey of self-discovery within the film, I have come to the understanding that I have spent nearly 20 years experiencing anxiety attacks, which are exacerbated by media appearances and public facing events.
