I'm from a Tech and Science background (unfinished Physics degree, most-definitelly-finished EE degree and then about 2 decades at the bleeding edge of Informatics) and some years ago came in contact with the Theatre Acting world for a couple of years whilst living in London (UK), doing various short courses, seeing fringe Theatre and getting acquainted with various (not famous) actors and directors.

Most were surprisingly (for me, at the time, with my pre-made ideas from my Science background and 2 decades in Tech) intelligent people.

Good acting using modern acting techniques and good directing do require quite a lot of brains to pull do well, IMHO, since in things like method acting well before there's any acting of what's on a script, there's a whole process of analysing them and various techniques for discovering the emotions of the character (best I can describe in a short space), at least for stage acting.

The only main difference in capabilities, I would say, is that at least in Acting there is a much higher proportion of Extroverts than Introverts, the very opposite of the proportion in Science and Tech, and Introverts are the ones with the personality type that's detailed oriented and hence more likely to come up with things like new or changed processes for doing things (IMHO).
