Here's what we know:
* No definitive proof: There's no widely accepted evidence that proves the existence of such a film.
* Numerous claims: Over the years, various individuals have claimed to have seen or owned a copy of this film. However, these claims have never been substantiated with concrete proof.
* Historical context: Marilyn Monroe began her career in the late 1940s and was already starting to gain attention. It's unlikely she would have participated in a stag film at that stage of her career.
* Limited evidence: Some alleged stills from the film have surfaced, but their authenticity is highly questionable.
* Possible forgeries: Many believe the claims are simply attempts to capitalize on Marilyn Monroe's fame and generate profit from potential forgeries.
Therefore, it's highly likely that the alleged 1948 stag film featuring Marilyn Monroe is a myth. The lack of concrete evidence, the potential for financial gain, and the historical context make it highly improbable.
It's essential to be critical of information circulating online and to rely on credible sources.
