EPISODE VIII: DUTIFUL DROIDS!

Loyal droids serving far different kinds of masters - cute BB-8 and shifty BB-9E - pose for a special merchandise/publicity image for The Last Jedi.

Brian Herring, one of the most recognisable faces behind BB-8's functioning, is interviewed:

EPISODE VIII: GOING EYE-TO-EYE!

Our lovable Resistance droid BB-8 squares up to his First Order counterpart in BB-9E, for a great toy marketing image. Though we had seen Astro Droids fight in The Clone Wars animated series first season of 2008, the chance for a big screen, live-action conflict between this unique duo for The Last Jedi was, surprisingly, an option not taken by the film's production team. A shame, as it would surely have been a crowd-pleasing extra moment...

At least there was some special footage for this Verizon ad:
