This past Sunday came up short for new 'Game of Thrones' season 4 trailers, instead offering a new look at 'Office Space' creator Mike Judge's tech comedy 'Silicon Valley,' but HBO has us covered. Check out new character-themed teasers for 'Game of Thrones' season 4, along with a giant cache of posters that ominously warn us, "Valar Morghulis"!

Courtesy of Entertainment Weekly, the latest Tyrion teaser for 'Game of Thrones' season 4 arrives as a somewhat CG-looking trip through the King's Landing dungeons, culminating on a chained Tyrion bleakly wondering if his visitor has arrived for a "last look." In addition to EW's five Lannister-themed "Valar Morghulis" (All Men Must Die) posters, IGN has another round of posters and teaser from the Stark side, including Littlefinger delivering some seriously creepy words to poor Sansa Stark.

In the meantime, there’s always photos, trailers and teases for the April 6 premiere, while HBO has cast in known roles Joel Fry as Hizdahr zo LoraqRoger Ashton-Griffiths as Mace TyrellPedro Pascal as Prince Oberyn Martell, Indira Varma as Oberyn’s lover Ellaria Sand, Yuri Kolokolnikov as Styr, Magnar of Thenn, and ‘Sherlock’ star Mark Gatiss as Tycho Nestoris. ‘Treme”s Michiel Huisman will replace Ed Skrein as Daario Naharis, and Hafthor Julius Bjornsson will take over the role of Gregor “The Mountain” Clegane from Ian Whyte, among other recastings.

You can check out the teasers and the full compliment of posters above and below. What do you most want to see from the April 6 'Game of Thrones' season 4 premiere?

UPDATE: HBO unveiled all 20 of the new 'Game of Thrones' character posters, along with the three Tyrion, Starks and Daenerys teaser videos.
