HBO is creating its own version of Must See TV on Sunday, April 12, with the season premieres of Game of Thrones, Silicon Valley and Veep.

Game of Thrones will lead off the night at 9 p.m. ET/PT, beginning its 10-episode fifth season, which will adapt material from the fourth and fifth novels of George R.R. Martin's sprawling fantasy series, A Feast for Crows and A Dance with Dragons. The new season will expand the action to Dorne and include flashbacks, adding to the already-sprawling cast such actors as Alexander Siddig, Adewale Akinnuoye-Agbaje and Jonathan Pryce.

Mike Judge's comedy Silicon Valley's will kick off its sophomore season at 10 p.m., followed by the return of Julia Louis-Dreyfus for the fourth season of Veep at 10:30.
