Without spoiling too much for those sensitive amongst us, that other popular star franchise has used digital technology to de age some of their characters (i.e. ANH-era Leia in Rogue One) and bring back Peter Cushing's Grand Moff Tarkin in the same film. This motion capture tech was probably best pioneered by Robert Zemeckis. We aer already seeing this technology being used in Star Trek as trailer-by-trailer we are seeing Brent Spinter become Lt Commander Data once more (slowly and not without criticism!), but how would you feel about further use? Could we see young actors being used to digitally become William Shatner and Leonard Nimoy circa 1966? Howe would you feel about it? Or for flashbacks in the new Picard show? I think Shatner has already spoken about it!
