I think the thing is that, given relative size, even American B listers have more global prominence than British A listers who haven't made it into Hollywood.
Meghan wasn't even B list though. Suits was reasonably popular, but as posters above have said, even those who liked the show didn't necessarily know who Meghan was. It wasn't that type of show. She could have walked down any street in America and nobody would have looked twice at her.
Anyway, Suits was just put on Netflix presumably due to the royal thing, and has broken some Netflix records in America.
Why do you think it's 'due to the royal thing'?
I agree that her name probably did arouse some interest in the show. But the strikes meant that there was little original content and a 9 series show with hundreds of episodes was attractive. Her name alone wasn't enough to sell her limp podcasts, so I don't think the 'royal thing' guarantees success unless the product is good.
just think of former new entry darlings like Jennifer Lawrence;
You're not seriously comparing Meghan to an Oscar winning actress who was the star of a massive trilogy? Who was half Meghan's age when she became famous? Who had extremely lucrative contracts with high end fashion houses?
Come on!
