Trailer screen shot from “Rick and Morty.” (Adult Swim)

“GETTING darker.”

So promises Rick Sanchez in a new trailer that heralds the next full season of Adult Swim’s “Rick and Morty.”

The third season technically debuted April 1, when creators Dan Harmon (“Community”) and Justin Roiland (“Adventure Time”) dropped a surprise episode. But the animated hit’s full 10-episode season will begin July 30.

Roiland, of course, voices Rick, the mad-genius scientist who wreaks intergalactic havoc, and the show co-stars the voices of Sarah Chalke, Chris Parnell and Spencer Grammer.

Let’s get darker.
