TVLine Items: Alphas and Thrones Castings, Stamos in Revived Dead Lawyers, and More

Alphas is spicing up its already extraordinary debut season with a slew of special, genre TV-friendly guests. Here’s when you can look forward to seeing faves from shows such as Terminator and Star Trek: TNG hit Syfy this summer:

For starters, erstwhile Bionic Woman Lindsay Wagner will bring her Warehouse 13 character, Dr. Vanessa Calder, to Alphas on Aug. 15. Geek goddess Summer Glau appears Aug. 22, followed the week thereafter by her Terminator: The Sarah Connor Chronicles costar-turned-Raising Hope grandpa Garret Dillahunt.

Next, as previously reported by TVLine, Lost‘s Rebecca Mader will pop up on Sept. 12, playing an alpha whose abilities must be seen to be believed. That same episode also guest-stars Brent Spiner (Star Trek: The Next Generation).

Ready for more of today’s TV dish? Well…

• Gemma Whelan (Gulliver’s Travels) has been tapped to play Theon’s fierce older sister, Yara — aka the character known in the books as Asha — during the second season of HBO’s Game of Thrones, per EW.com.

• Bravo announced Tuesday the renewal of three series: The Real Housewives of Orange County will be back for a seventh season; Top Chef Masters has been picked up for a fourth; and Million Dollar Listing LA has landed a fifth installment. In addition to the returning shows, the cabler has ordered three new reality projects: Around the World in 80 Plates, a globe-trotting culinary competition; Paint the Town, a docu-drama about New York-based art gallery employees; and Newlyweds: The First Year, which follows a half-dozen couples from the day they wed to their first anniversary.

Ana Gasteyer has been bumped up to recurring player on ABC’s new comedy Suburgatory (premiering Sept. 28), EW.com reports. The Saturday Night Live funnylady guest-stars in the pilot as an overbearing, rose-pruning neighbor of Jeremy Sisto’s new ‘burbs resident.

• Sony TV is reviving Dead Lawyers, a high-concept legal drama that Syfy put on the backburner nearly eight years ago and now will be pitched to other outlets, Deadline reports. John Stamos is tapped to star in the new pilot, with Justified showrunner Graham Yost co-writing and executive-producing.
