ARROW"Arrow" heads back to air on January 15, and the CW has released the full episode description for "Tremors," the midseason premiere. The episode also introduces villain Shrapnel, played by "Firefly" alumnus Sean Maher.

Oliver must tackle a new threat to the city when bombs start to go off in Starling City. Felicity discovers the person setting them off is Mark Sheffner (guest star Sean Maher), a man who goes by the nickname Shrapnel. Arrow discovers Shrapnel's next target is Sebastian Blood's (guest star Kevin Alejandro) "Unity Rally" and tries to talk the alderman out of hosting it, but he refuses. Arrow sets off to stop the bombing, but Shrapnel tricks him and traps him in a bomb-laced antique store where he is unable to move without setting off the device. While Felicity helps Oliver, Diggle races to the plaza to find the bomb before it goes off. Meanwhile, Roy continues to hide his new strength from Thea but, after she witnesses his super strength in action at the rally, she demands answers. Laurel's suspicions about Sebastian grow stronger once she learns that he grew up with Cyrus Gold, the man who killed Lance's partner. After Donner (guest Star Dylan Bruce) refuses to help her investigate, she turns to Arrow for help.

AMAZING SPIDER-MAN 2The "Amazing Spider-Man 2" Daily Bugle viral tumblr continues to be the place to watch for offhand mentions of characters integral to the Spider-Man canon. This time, it's a mention of Professor Miles Warren (better known by his comic book villain name, The Jackal), who teaches a cloning class at Empire State University.

t's either a sign of the times or a sign of the apocalypse...

Manhattan's Empire State University announced a new class for the 2014 fall semester in advanced biogenetics that will actually require the successful cloning of a living creature. Introduction to Live Cloning, taught by noted geneticist Professor Miles Warren, is the first class of its kind anywhere in the world.

When asked about the ethical aspects of teaching a class on how to clone living cells, Warren said, "Our responsibility is to educate our students and prepare them for life. For those who study genetics or biology, cloning will be a fact of life."

The ethical aspects of cloning are irrelevant to Warren, who added, "We are cloning single-celled amoeba. Maybe one day we'll work our way up to mice. There is no ethical dilemma. Save your red flag for when I start cloning co-eds..."

DOCTOR WHOAin't It Cool News has posted quotes from "Doctor Who" showrunner Steven Moffat from an interview with "Doctor Who Magazine," discussing the particulars of Peter Capaldi's Doctor and how it'll differ from Matt Smith.

"There would be little point in making as radical a change as we've made unless you're going to go quite different with the Doctor," Moffat told "Doctor Who Magazine." "The last two Doctors have been brilliant, and have been your 'good boyfriend' Doctors. But the Doctor isn't always like that. There is the sort of Tom Baker, Christopher Eccleston end of the spectrum, where he is mad and dangerous and difficult. ... We need the kick-up-the-arse Doctor, in a way, to frighten you and make you think, oh, it's a different show again."

THE SECRET SERVICEIn an interview with CBR, Mark Millar discussed his role as an executive producer for "The Secret Service" as well as some of the casting decisions.

"Actually, as an exec producer all the work really gets done before shooting and after," Millar told CBR. "The actual filming is where the director just reigns supreme so you sit back, do the odd set visit, say hello to everybody and try to keep out of the way. Matthew and Jane wrote the screenplay last year, and then we had a few months of watching casting tapes every day. Matthew's quite funny about this -- you'll be in a supermarket and he phones you saying he's found a new guy who might be good for the leading kid and you say you're literally buying beans and he'll ask you to jump in a taxi, get home and check this guy out on the computer. This happened about three times a week as he's endlessly enthusiastic, which is really brilliant. So there's all that chatter and looking at designs and so on, but it's really just a gracious thing for him to do as he knows exactly what he's doing. He's one of the best directors in the world."
