Fox released Niagara in January 1953 with Monroe as Rose Loomis, her first clear top-billed starring vehicle in colour. This Fact is that public theatrical instrument, not Gentlemen Prefer Blondes and not a later tourist caption of the Falls.
Context
A starring thriller is a public-image and knowledge object: audiences saw a named actress carry a picture.
Marilyn Monroe’s documented role is bounded by other offices and collaborators named in the sources below.
Henry Hathaway directed; Fox marketed the colour and the walk. She is the named lead, not the only author of the picture.
Why it matters
A widely distributed starring film is an access path to a public performance. Confidence high on the release, medium on any unique literacy series.

What the sources establish
AFI Catalog filmography and Britannica independently date Niagara as a 1953 starring release.
Established: Niagara as a 1953 Fox starring release under her name. Not established: that the Falls location is her authorship of tourism.
Marilyn Monroe did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A colour thriller is not MMP. Keep January 1953 distinct from July’s musical.
