“Doctor Who” – Regeneration happens. And so it is that Peter Capaldi finally gets the keys to the TARDIS this week. Capaldi, a 56-year-old Scottish actor and lifelong “Who” fan, becomes the 12th Time Lord in the wildly popular franchise and he appears poised to battle Cybermen, Daleks and any other heinous villains that dare come his way. The feature-length season opener, “Deep Breath,” promises a “pulse-racing adventure through Victorian London.” We’re so ready. 8 p.m. Saturday, BBC America.
SUNDAY: Uh oh. On “The Last Ship,” they’re asking for volunteers to participate in human trials of Rachel’s (Rhona Mitra) vaccine and the resulting effects could be nightmarish. 9 p.m., TNT.
SUNDAY: It’s the next-to-last episode of “True Blood” and we’re still wondering if peace will ever come to the beleaguered residents of Bon Temps. Um, probably not tonight. 9 p.m., HBO.
