Charlatan (Czech: Šarlatán) is a 2020 biographical historical drama film directed by Agnieszka Holland and written by Marek Epstein, loosely based on the healer Jan Mikolášek (1889–1973), who cured hundreds of people using plant-based remedies.

[9] The life of Jan Mikolášek [cs], a well-known and successful Czech healer, who diagnosed and healed people using his intuition and his familiarity with plants.

[10] In real life, Jan Mikolášek was tried and convicted in 1959 of tax and other offenses, but not for murder by strychnine poisoning, was released in 1963, and died in 1973.

The critics consensus says: "Charlatan's slightly dry approach is offset by unique filmmaking flourishes and a fascinating story that make this an engaging, albeit unusual, biopic.

"[24] Metacritic assigned the film a weighted average score of 66 out of 100, based on seven critics, indicating generally favourable reviews.

(...) This is a forceful, capable movie with an interesting story to tell but its potency consists in a handful of gripping episodes, the most startling being when the young Mikolášek has developed a love of herbs and a vocation for healing.

[30] On 6 March 2021, Charlatan won five Czech Lion Awards including Best Picture, Best Director (Agnieszka Holland), and Best Lead Actor (Ivan Trojan).
