“Game of Thrones“ fans, now our watch begins. It shall not end until… 9pm Sunday, April 12, when the ten-episode fifth season premieres on HBO.

The return to Westeros kicks off a night of big premieres on the premium cable channel,  leading in to the second season premiere of “Silicon Valley” at 10pm and the fourth season premiere of “Veep” at 10:30pm. The premiere dates announcements were made during HBO’s presentation at the Television Critics Association’s Winter Press Tour on Thursday afternoon.

HBO also announced the renewal of “Real Time with Bill Maher” for that show’s 14th and 15th seasons, each with 35 episodes, set to premiere in 2016 and 2017 respectively. On the documentary front, the Laura Poitras-directed Edward Snowden documentary “Citizenfour” makes its HBO debut at 9pm Monday, February 23. Prior to that doc’s premiere, however, comes the premiere of “The Jinx: The Life and Deaths of Robert Durst,” airing Sundays between February 8 and March 15. Directed and produced by Andrew Jarecki, and filmed by Marc Smerling, the Oscar-nominated pair who brought us Capturing the Friedmans,  this is expected to be a high profile cinema verité series that’s drawing comparisons to the overwhelming popularity of the podcast Serial.

It’s also the second cable production that explores the story of Robert Durst, the billionaire who was accused of three murders over the past three decades but has never been convicted. Investigation Discovery’s upcoming series “Vanity Fair Confidential” will present an episode on the Durst case.  (That series premieres on Monday, January 19 at 9pm.)

Over on Cinemax, the network confirmed that “Strike Back” is set to return this summer for its fourth and final season, and the channel’s breakout drama “The Knick,” starring Clive Owen, will return for a second season in the fall. Exact premiere dates and timeslots have yet to be announced.

Missing from today’s announcements was a premiere date for the highly anticipated series “Westworld,” due to premiere on HBO later this year, but the channel’s upcoming comedy “The Brink,” with a cast that includes Jack Black, Tim Robbins and Pablo Schreiber, will be on the air this summer.
