I just stumbled upon the story from 2021 that one orc in The Lord of the Rings from director Peter Jackson was modeled after Harvey Weinstein:
One orc among many in the Lord of the Rings movies was designed to resemble Harvey Weinstein as a “sort of fuck you” to the notorious producer, Elijah Wood, who played the hobbit Frodo in the series, told a Hollywood podcast.
From this Guardian article
I was not able to find any sources not based on the interview with Eljiah Wood to confirm this. Has this ever been confirmed by another person involved in the film trilogy or is Eljiah Wood the only source?
In an interview with The Friendship Onion (Podcast by Dominic Monaghan and Billy Boyd), Sean Astin mentiones that there was an Uruk-Hai that looked exactly like Harvey Weinstein. However, he mentions with no word that it was intentional:
So, we have three of the main actors of the films and they mention with no word that said similarity was intentional. That's what makes me suspicious.
