HBO is hunkered down in Austin, TX this week for South by Southwest (SXSW), the annual festival for the film, television and interactive industries.

Following the big reveal last week of the premiere date for season 7 of Game of Thrones, showrunners David Benioff and D.B. Weiss, along with actors Maisie Williams (Arya Stark) and Sophie Turner (Sansa Stark) took the stage at SXSW to talk about the future of the series.

Pop music devotees may be intrigued to hear that Ed Sheeran—Maisie is a huge fan—will make a guest appearance in season seven. He joins a long list of musicians who have made cameos on the series, including Will Champion from Coldplay (season 3), Gary Lightbody from Snow Patrol (season 4) and the metal band Mastodon (season 5).

And speaking of cameos, Vice President Joe Biden and wife Jill took a break from their own SXSW activities to meet the cast and crew of GoT backstage (pictured, right). 

The crew from GoT also revealed that the eighth and final season will have only six episodes. While the shorter season may disappoint fans, there was also talk of a potential spinoff from HBO, though no further details were discussed.

After a stop on the Iron Throne, the cast of Veep—plus showrunner David Mandel—participated in a panel discussion moderated by real-life political analyst Chuck Todd of NBC. Fans attending the talk took home a limited-edition poster (pictured, left).

David Mandel and Veep cast members Timothy Simons and Matt Walsh also sat down with Kara Swisher at SXSW to record a special edition of her Recode Decode podcast. Watch it here, and then be sure to check out the new trailer for Veep, which returns to HBO April 16 (warning: contains typical Selina Meyer vulgarisms).
