 "markdown": "# The Belles of St Trinian's\n\n**The Belles of St Trinian's** is a 1954 British comedy film directed by Frank Launder, the first of a series of films based on Ronald Searle's cartoons about an anarchic British girls' boarding school. [Alastair Sim](https://www.edgepedia.org/alastair-sim) stars in a dual role as headmistress Millicent Fritton and her bookmaker twin brother Clarence, and the plot centers on a horse-racing scheme involving the sultan's racehorse Arab Boy.<sup>[1](https://www.tcm.com/articles/1399491/the-belles-of-st-trinians)</sup><sup> • </sup><sup>[2](https://www.comedy.co.uk/film/the_belles_of_st_trinians/)</sup>\n\n| Key fact | Detail |\n|---|---|\n| Release | UK release 28 September 1954; produced autumn 1953; distributed by British Lion<sup>[2](https://www.comedy.co.uk/film/the_belles_of_st_trinians/)</sup> |\n| Director and writers | Directed by Frank Launder; screenplay by Launder, Sidney Gilliat, and Val Valentine<sup>[3](https://www.rottentomatoes.com/m/1001994-belles_of_st_trinians)</sup> |\n| Lead performance | Alastair Sim as Miss Millicent Fritton and her brother Clarence Fritton, one role played in drag<sup>[1](https://www.tcm.com/articles/1399491/the-belles-of-st-trinians)</sup> |\n| Supporting cast | Joyce Grenfell as P.W.

With Princess Fatima's £100 placed on the horse to clear the school's debts, and bets made by the girls themselves, the staff and fourth form battle the sixth form to keep or return Arab Boy in time for the race.<sup>[2](https://www.comedy.co.uk/film/the_belles_of_st_trinians/)</sup> [Everything](https://www.edgepedia.org/everything) comes to a head on [Parents' Day](https://www.edgepedia.org/parents-day), when a melee breaks out: punters backing Arab Boy take drastic steps to ensure he reaches the race on schedule, while others work to keep him from being taken away.<sup>[6](https://videolibrarian.com/reviews/classic-film/the-belles-of-st-trinian%E2%80%99s/)</sup> Subplots include education ministry inspectors seduced by the older girls and added to the teaching staff, a field hockey match that turns into a free-for-all, and sports trophies that disappear at the flick of a light switch.<sup>[6](https://videolibrarian.com/reviews/classic-film/the-belles-of-st-trinian%E2%80%99s/)</sup> The police attempt to infiltrate the school by installing Sergeant Ruby Gates as the games mistress.<sup>[10](https://www.cinemaessentials.com/2020/09/the-belles-of-st-trinians-1954-alastair-sim-film-review.html)</sup>\n\n## Origins in Searle's cartoons\n\nRonald Searle's cartoons about the rowdy, larcenous girls of St. Trinian's School for Young Ladies had appeared in humor magazines beginning in 1941, while the cartoonist was still serving in World War II, and were later collected in the books *Hurrah for St. Trinian's* (1947), *Back to the Slaughterhouse* (1951), and *Souls in Torment* (1953).<sup>[1](https://www.tcm.com/articles/1399491/the-belles-of-st-trinians)</sup> The first cartoon appeared in *Lilliput* magazine in 1941, with the second not until 1946, a gap explained by Searle's capture and internment by the Japanese during the war; many of the images were sketched during that period.<sup>[5](https://etheses.whiterose.ac.uk/id/eprint/12647/1/PhD%20WHOLE.pdf)</sup><sup> • </sup><sup>[7](https://bura.brunel.ac.uk/bitstream/2438/14389/1/FulltextThesis.pdf%20)</sup> The Guardian's Philip French described the cartoons as depicting a girls' boarding school \"populated by gangsters in gymslips\" and credited them with making Searle thought of as Britain's answer to [Charles Addams](https://www.edgepedia.org/charles-addams).<sup>[8](https://www.theguardian.com/film/2007/dec/23/comedy.girlsaloud)</sup>\n\nWriter-director Frank Launder, working with his partner Sidney Gilliat, used the cartoons as the inspiration for the 1954 film.<sup>[6](https://videolibrarian.com/reviews/classic-film/the-belles-of-st-trinian%E2%80%99s/)</sup> According to IMDb trivia, the role of Miss Fritton was written for [Margaret Rutherford](https://www.edgepedia.org/margaret-rutherford), and Alastair Sim took over when her services could not be secured.<sup>[9](https://www.imdb.com/title/tt0046766/)</sup>\n\n## Production and reception\n\nThe British Lion Film Corporation hired the veteran filmmakers Launder and Gilliat to create the film, produced at a time when food rationing had only just been phased out in Britain.<sup>[11](https://www.edgemedianetwork.com/story/302130)</sup> Production companies were London Film Productions in association with British Lion Films, with Stanley Pavey as cinematographer, Thelma Connell as editor, and a score by Malcolm Arnold.<sup>[10](https://www.cinemaessentials.com/2020/09/the-belles-of-st-trinians-1954-alastair-sim-film-review.html)</sup> Filming locations included All Nations College at Easneye, Stanstead Abbotts, Hertfordshire, for wideshot exteriors.<sup>[9](https://www.imdb.com/title/tt0046766/)</sup>\n\nThe film was one of the most popular British films of 1954, ranking third at the UK box office that year.<sup>[10](https://www.cinemaessentials.com/2020/09/the-belles-of-st-trinians-1954-alastair-sim-film-review.html)</sup><sup> • </sup><sup>[5](https://etheses.whiterose.ac.uk/id/eprint/12647/1/PhD%20WHOLE.pdf)</sup> On Rotten Tomatoes it holds a 67% Tomatometer from 6 reviews and a 68% Popcornmeter from more than 1,000 ratings.<sup>[3](https://www.rottentomatoes.com/m/1001994-belles_of_st_trinians)</sup> Critics have singled out Sim's dual performance: the Monthly Film Bulletin wrote that \"this transportation of Ronald Searle's awful school has been effected with the greatest possible success,\"<sup>[3](https://www.rottentomatoes.com/m/1001994-belles_of_st_trinians)</sup> and a Television Heaven retrospective ranked it 94th in the BFI's top 100 British films, calling it infinitely superior to the sequels that followed.<sup>[12](https://televisionheaven.co.uk/assets/magazines/tvh_remthis-compressed-%28final%29.pdf)</sup> Reviewers have also noted weaknesses in construction, with subplots that peter out, while crediting Sim's comedic timing and the rowdy students for carrying the film.<sup>[3](https://www.rottentomatoes.com/m/1001994-belles_of_st_trinians)</sup>\n\n## Sim's dual role\n\nIn the film, Sim takes on a dual role: he portrays Clarence, the glib bookmaker, as well as Clarence's sister, Millicent Fritton, the school's head. Fritton is a figure shaped by late Victorian times and a principled liberal schooling, and she watches the girls' mischief with a fond, eye-rolling tolerance.<sup>[8](https://www.theguardian.com/film/2007/dec/23/comedy.girlsaloud)</sup><sup> • </sup><sup>[6](https://videolibrarian.com/reviews/classic-film/the-belles-of-st-trinian%E2%80%99s/)</sup> The drag performance became one of the best known and liked in UK film history, though it was probably not the first time a main character in a British film was played in drag.<sup>[11](https://www.edgemedianetwork.com/story/302130)</sup> Sim approached the 1957 sequel with some reluctance, and his cameo of two scenes in *Blue Murder at St. Trinian's* is brief; the impact of his performance in the first film was such that some commentators are convinced he stars in the entire series.<sup>[13](https://shura.shu.ac.uk/17393/1/31410_Wilson.pdf)</sup>\n\n## The St Trinian's series\n\nThe film's success spawned three sequels between 1957 and 1966: *Blue Murder at St Trinian's* (1957), *The Pure Hell of St Trinian's* (1960), and *The Great St Trinian's Train Robbery* (1966), followed by an unsuccessful reboot in 1980 (*The Wildcats of St Trinian's*) and a second reboot in 2007 that led to a further sequel in 2009.<sup>[6](https://videolibrarian.com/reviews/classic-film/the-belles-of-st-trinian%E2%80%99s/)</sup><sup> • </sup><sup>[10](https://www.cinemaessentials.com/2020/09/the-belles-of-st-trinians-1954-alastair-sim-film-review.html)</sup> The 2007 film, directed by Oliver Parker and Barnaby Thompson, cast [Rupert Everett](https://www.edgepedia.org/rupert-everett) as Miss Fritton; Philip French judged it raucous and largely misjudged, though a preview audience of girls aged seven to fourteen found it hilarious.<sup>[8](https://www.theguardian.com/film/2007/dec/23/comedy.girlsaloud)</sup> The St Trinian's films also made the school uniform as fancy dress a widespread element of English cultural life, to the point that *The Times* could refer to \"Trinianisms\" confident that readers would understand the term.<sup>[5](https://etheses.whiterose.ac.uk/id/eprint/12647/1/PhD%20WHOLE.pdf)</sup>\n\n## References\n\n1.
