It might seem a bold assertion, but there's a reason that classically-trained Shakespearian actors are often cast in sci-fi shows (Patrick Stewart and Ian McKellen as perhaps the most famous examples). They're trained to convey more information through intonation and gesture so that you don't need to know the words they're saying, which translates well to performances in invented languages.
It'd be extra convincing if there were more non-Brits with Shakespeare backgrounds that became big Sci Fi actors to point to. There are American Shakespeare companies or performances, but it's a much smaller deal.
ETA: another source of great sci-fi actors was Hammer Films, which produced Christopher Lee and Peter Cushing. Great American sci-fi actors come from more backgrounds because there's more acting jobs in America.
I've always had to use captions and backtrack/pause.

I feel like The Tempest is lower than I expected. I think it is often liked for not so easily fitting into one of the traditional genres. I feel like I see productions advertised reasonably frequently but I also did this at school so maybe I notice them more for that reason.
I think the OP has the same favourite play as fictional classics professor Jim Lloyd, which is interesting for some, I guess.
