maybe Star Trek shoud do a "Rogue One" type movie
Khans exile on Ceti Alpha 5 with Javier Barhem as Khan (and CG characters of 1960s Shatner, Nimoy etc at the start and 1980s Walter Koenig and Paul Winfield at the end)
Trek followed Wars into movies in 1979.. maybe Trek should follow Wars again into spin off movies
