Q: Is it true that characters from the hit Disney film “Frozen” are coming to “Once Upon a Time”? Judging by the tease from this season’s finale, I’d say yes. — Steff S. in Florida
A: That is indeed true, Steff. Characters loosely based on Kristoff, Anna and Queen Elsa — who will be played by Scott Michael Foster (“Greek”), newcomer Elizabeth Lail and Georgina Haig (“Fringe,” “Reckless”), respectively — will cool their heels in Storybrooke, Maine, in season four of ABC’s red-hot fantasy/drama series.
The “Frozen” story arc on “Once Upon a Time” is expected to pick up after the events of the film.

Q: I know how busy Benedict Cumberbatch and Martin Freeman are, but please tell me that there will be another season of “Sherlock.” — Jenny T., via email
A: I am happy to report that there shall indeed be another season of the BBC/PBS hit mystery series based on Sir Arthur Conan Doyle’s detective book series.
The show will return with a three-episode fourth season, which will start with a one-off Christmas special (most likely) in December 2015.
You read me right: That’s a Christmas special plus a regular three-episode season.  
According to “Sherlock” co-creator and actor Mark Gatiss: “At last! It’s always special to return to ‘Sherlock,’ but this time it’s even more special as we’re doing ... a special! Not only that, we’ll then be shooting three more episodes, which will take Sherlock and John Watson into deeper and darker water than ever before. The whole ‘Sherlock’ team is terrifically excited to return for four new adventures. The game is on — again!”
