#Q ORIGINAL QUESTION

Regarding the film Monster (2023), who was the most famous actor in it at the time of release, and what other notable films were they in?

#M ANNOTATED LLM RESPONSE

At the time of its release in June 2023, the most famous and critically acclaimed actor in Hirokazu Kore-eda’s Monster (Kaibutsu) was Sakura Ando. While the film features an ensemble of high-profile Japanese stars, Ando held the most significant international and domestic profile due to her previous collaboration with Kore-eda and her reputation as one of Japan's most decorated contemporary actresses.

Sakura Ando (Role: Saori Mugino)

At the time of Monster's release, Ando was already a household name in Japan and a favorite of international film festivals. She plays the mother, Saori, who first notices her son's troubling behavior.

[4] Ando won Best Supporting Actress for 'A Man' at the 46th Japan Academy Film Prize in March 2023, three months before 'Monster' was released.
[5] Eita Nagayama performed under the mononym 'Eita' from 2002 to 2019 before reverting to his full name in 2020.

#O MISSED POINTS & OVERSIGHTS

Medium
Ryuichi Sakamoto's Score

While not an actor, the film was heavily marketed on being the final score by legendary composer Ryuichi Sakamoto (who died shortly before release), which was a major factor in its fame and profile.

Low
Child Actors' Prominence

The film centers on the two boys, Soya Kurokawa and Hinata Hiiragi. While they weren't 'famous' beforehand, their roles are the narrative core, which the summary glosses over to focus on the adults.
