Regarding the 1966 film *Persona*, directed by Ingmar Bergman, its rating varies by country and era. Because the film was released before many modern rating systems were standardized, it has a complex classification history.
### **Official Ratings**
* **United States (MPAA):** The film is **Not Rated**. At the time of its U.S. theatrical release in 1967, the MPAA’s letter-grade system (G, PG, R, X) did not yet exist (it launched in late 1968). Even in later re-releases and home media versions (such as The Criterion Collection), the film has generally remained "Unrated," though it is widely considered to contain "R-rated" or "NC-17" level content by modern standards.
* **United Kingdom (BBFC):** The film was originally given an **'X' certificate** in 1967 (suitable for ages 16 and over). In modern re-classifications (2002, 2018), it has been rated **15** for strong sex references, nudity, and violence.
* **Sweden:** It was originally rated **15** (suitable only for those 15 and older) by the Swedish Media Council (*Statens biografbyrå*).

### **Elements Contributing to the Rating**
The film is celebrated for its avant-garde and transgressive nature, which challenged censors in the mid-1960s. Several specific elements contribute to its adult classification:
#### **1. Explicit Sexual Dialogue (The Beach Monologue)**
The most famous and controversial sequence is a long, static shot where Sister Alma (Bibi Andersson) describes a sexual encounter on a beach involving herself, another woman, and two young boys.
* **Detail:** While no sexual activity is shown on screen, the description is incredibly vivid and clinical, referencing **masturbation, ejaculation, fellatio, and group sex.** This monologue was so explicit for the 1960s that it faced heavy censorship and remains one of the most significant reasons for its high age rating today.
#### **2. Graphic and Disturbing Imagery**
The film’s prologue and various dream sequences feature jarring, "subliminal" images that contribute to its "15" or "X" ratings:
* **Nudity:** The prologue contains a very brief, nearly subliminal shot of an **erect penis**, which was cut from many international prints for decades.
* **Violence and Gore:** There are close-up shots of a **nail being driven into a human palm**, a **sheep being slaughtered** (throat slit), and newsreel footage of a **Buddhist monk’s self-immolation** (the famous 1963 footage of Thích Quảng Đức).
* **Body Horror:** In one scene, a character scrapes her fingernails up her own arm until she **draws blood**, which she then offers to the other character to drink (metaphorical vampirism).
#### **3. Psychological Maturity and Themes**
The film deals with deeply disturbing psychological themes that make it unsuitable for younger audiences:
* **Identity Dissolution:** The film explores the "merging" of two women's personalities, featuring distressing shots where their faces are superimposed or combined into a single, haunting composite.
* **Abortion and Motherhood:** The characters discuss **abortion** and a mother’s intense, visceral hatred for her child, themes that were considered highly taboo and "emotionally violent" at the time of release.
* **Existential Dread:** The overall atmosphere is one of profound mental breakdown and silence, which the BBFC classifies as "moderate horror images" due to its unsettling nature.
