The hook seems to be that an ambitious actress must give the performance of her life to save her life — and her career –from the consequences of a murder in which she is implicated.

So,?you want to do a story with an anti-hero protagonist. Okay, but you still need ?to have an element in the story — and logline — ?that represents a socially acceptable motive (for example, one that affirms a family value) that an audience can accept and empathize with.

Like in “Breaking Bad”. ? Walter White’s motivation was to provide for his family after his death. ?He himself had no expectation of benefiting from his crimes. ?He was doing the wrong thing for the right reason, for the sake of his family, not himself.

It seems to me the story needs a right reason for her to do the wrong thing.?

Also, initially, Walter White is a decent guy. There may have been nothing about him to admire, but you could still like him because neither was there anything about him to ?dislike. ?His ?character and plight ?was one an audience could identify with. ?In contrast, your proposed anti-hero fame is characterized as obsessed with fame — not exactly an endearing or sympathetic?trait from the git-go.

fwiw

Unless your story gets him back down to earth in early Act 2 to locate and rescue his family, ?he seems to be trapped in outer space in the role of a mentor/adviser. ?In that case, the more interesting challenge and story would seem to be how his family follows his survivalist tips transmited from outer space.

So it seems the real protagonist would be either his wife or his child who must come of age at hyper-speed and acquire survival skills.?(After all the real focal point of dramatic tension is not on the person who knows what to do, but on the one who has to do it in spite of all adversities and anxieties.)

Consequently, if he’s trapped in outer space for the bulk of the story, then it seems to me that the story ought to be framed from the point of view of a family member on earth, the one pivotal to following his helpful hints.?

(BTW: Making the son a a teenage protagonist would certainly broaden the market for the film. The young adult audience is the sweet spot.)

fwiw.
