The various Star Trek series have a long history of exploiting the dark, parallel universe first created in the original series’ second season.
And what better villain for the revitalised, rebellious Kirk than a darker, evil version of himself?
But it has to be handled properly – and as an extra twist, what if the alternate Kirk was actually a woman? It would be a great role for a young actress and help to give more satisfying female roles in the film series.
Meanwhile, after the loss of his planet and his mother, the revelation of a goatee-sporting Evil Spock could send Zachary Quinto’s take on the character back over the edge again - and we all enjoyed it when Spock was going nuts.
Oh, and they could explore the very topical ethics of torture in true Trek debate style.
Our only real problem? The fact that they’re already in a slightly alternate universe – it might be too much for the sequel to delve into parallel worlds.
