The reason is that, by the time we (the public) know about their work in films/episodes, they have already finished doing that work. For example, as of 21 September, we know about episode 2.03, and that episode has already been filmed and it is, if not wraped, finishing post-production.

That's too the reason why actor pages say "portrayed" using past tense, because they have already finishing that particular portrayal
