Star Trek isn't my only passion and much like the Leonardo DiCaprio meme, I get a little excited when I spot a Star Trek actor in one of my other favourite shows! So, here you'll find actor crossovers who have also appeared in the Doctor Who universe, the Marvel multiverse, the DC Extended Universe, or the NCIS, erm, world. Going forward, I'll also be including actor crossovers from The Orville and Galaxy Quest, as well as actors from Babylon 5, Stargate and Battlestar Galactica productions.
