Well, first things first, I am not a worrier, not in the slightest. Perhaps you're thinking more 1w9 than 9w1?
Both of the characters you mention I can see possibly being 9s, although I see 1 more in both of them, maybe it's the J vs P difference? Also, watched the Mosquito Coast last night and Helen Mirren's character, "Mother", seemed very 9-like, getting to extremely unhealthy 9 at the end where she is unwilling to see that her husband is completely destroying her family's life. She will not assert herself against him even though it is more than warranted.
9 is a pretty versatile type, I think. I think it's easy- just like with any type- to focus on the more stereotypical representation of it. None of the characters mentioned are real people (obviously), so they're pretty one-dimensional. Guess I'm just saying you have to watch it with typing of this sort because it seems overly simplistic/ tends to reinforce stereotypes of the types.
Well, quite a few INFJs in this very forum claim they're 9w1s, so I don't think the difference lies in J/P. And, from what I've read in threads in the Enneagram Institute forum, 9w1s are usually more "cerebral" than 9w8s, who are more "grounded". And, well, while Nines are usually pretty passive, Ichazo (I think) says they acquire the traits of an unhealthy Six during moments of stress. I can see where you're coming from, though.
It's just, well, I kind of imagine 1w9 as being more contentious, like Mr. Spock or Prosecutor Edgeworth from the
Ace Attorney series. Neither of the characters I mentioned seems contentious - Miss Honey's main fault is that she refuses to act against her boss's tyranny due to her low self-esteem, thus enabling said boss to continue oppressing others.
To be frank, though, this is also kind of a part of my ongoing quest to find my type, but I figured a thread like this could be a good reference for future forumers.
Anyway, thanks for responding, brainheart! You rock, srsly.
EDIT: Hey, speaking of one-dimensonal, how about Chance the Gardener from
Being There as a 9w1 caricature?
