With Disco season 2 introducing us to Ethan Peck as Spock; it made me minder who would you cast as the remaining regular TOS characters in DISCO. Here's my choices Kirk - Connor Jessup McCoy - Alexander Koch Scotty - Cole Sprouse Sulu - Ross Butler Uhura - Ajiona Alexus Chekov - This was a difficult one considering he would be a teenager in DISCO's timeframe. I decided not to pick someone based on just their accent because it would limit my choices; but I feel Noah Schnapp would make a good Chekov as though there wouldn't be much reason to include him in the show. Chapel - They should cast Rebecca Romijn considering she was played by the same actor as Number One but if they don't wish to have Romijn potentially playing two characters at once Courtney Ford would be my alternative casting. Rand - I chose Emily Bett Rickards, although Rand's age was supposed to be 24 (which would make her a teenager in DISCO), that scene was deleted and her age has never been determined, considering how old she looked in the films I would make her 30s in TOS. So I would cast somebody older than a teenager in DISCO. I also considered including Arex and M'Ress from TAS but I realised since they would be make - up heavy so it wouldn't matter who would be cast.
