If you can't evaluate the special effects, music, sound and video editing, etc., how do you know whether its gonna hit or miss?
My examples would be for instance lorne greene - battlestar galactica, or alec guinness star wars - hit.
Or john travolta in that abortion battlefield earth.
John Travolta is an interesting example because he specifically did that one because of Scientology. Alec Guiness also pretty famously spoke ill of Star Wars; there's some pretty interesting reading on his
wiki page (and in the referenced articles if you care to dive deeper) about his reasoning and continued approach even after the sequels.
Honestly, I think it's like any role and just situational. Of course you have scripts that are just good on reading, or maybe a trusted production company, IP, or director. I've also read plenty of cases of actors who take on roles they're less thrilled about to be able to get passion projects funded. But of course, as with any movie, you certainly won't know if it'll be a hit or not until audiences actually get their hands on it.
