Westworld season 3 will feature some fun cameos from the creators of another popular HBO series.

There won’t be any more Game of Thrones coming to HBO in 2020, but this Westworld season 3 cameo could be the next best thing. Game of Thrones creators David Benioff and Dan Weiss will trade Westeros for Westworld in the show’s upcoming third season.

According to EW, the duo will play Delos technicians. Unfortunately, we have no idea what they’ll be working on.

After the huge fallout from season 2, we’re interested to see what Delos is up to and what their plans for the future are. We’re assuming Benioff’s and Weiss’s characters will somehow feature in William’s storyline, but very little is known about their cameo at this point.

Westworld season 3 premieres on HBO on March 15, where we’ll follow some of the hosts into the real world.

We still don’t know what characters will be returning, as Dolores escaped the park with some mystery minds, but we know we can’t wait to see how they adapt to their new surroundings.
