TVLine Items: Fox Drama Promotes Glee Grad, HTGAWM Trailer and More

Fox is increasing the amount of sugar in its new midseason drama Lookinglass.

Vanessa Lengies, who played the amusingly ridiculous Sugar Motta on Glee, has been promoted to series regular on the series formerly known as The Frankenstein Code, according to our sister site Deadline.

Lengies initially was booked as a guest star, playing Alexa, the “loyal and highly competent executive assistant” to Dilshad Vadsaria’s Mary, one of the twins who run the show’s titular social media company and bring back to life a disgraced, deceased sheriff.

Ready for more of today’s newsy nuggets? Well…

* ABC has dropped the Season 2 trailer for How to Get Away With Murder, and — spoiler alert — Viola Davis’ Annalise Keating manages to weep, smile and rage against a monster all in the course of 30 seconds. Watch it below (then scroll down for even more juicy tidbits)!

* Mariah Carey’s planned guest spot on Empire likely won’t come until the Season 2 finale — and will probably find the diva playing a character other than herself, creator Lee Daniels tells EW.com. “She’s giving us the hard assignment of trying to create a character,” Daniels noted, “which we’re doing right now.”

* Agents of S.H.I.E.L.D., Agent Carter, Jessica Jones and Daredevil are among the shows Marvel TV is showcasing at New York Comic-Con next month. (Get details here.)
