Movie actors with aphantasia?

Are there any aphant movie actors? If seems to me actors must have a great ability to imagine and visualize. Like, with CGI and green screens they can't see the alien or ghost or dinosaur that they are interacting with. Or staring into the camera as if it's your boyfriend breaking up with you or your dieing mother, shedding a tear. 

As a total aphant I can't even imagine how actors do this.
