On what date was the second teaser trailer for the DC series Lanterns released?

The second teaser trailer for the DC series Lanterns was released on May 18, 2026.

The second teaser offered more explicit connections to Green Lantern mythology than the first promotional material. It showed Hal Jordan wearing his Green Lantern suit and using his power ring to create green constructs. It also featured Ulrich Thomsen as Sinestro and drew attention to the idea of fear and the Yellow Lantern Corps.

The marketing developed in stages. The first teaser had been released on March 4, 2026, and was noted for presenting Lanterns as a grounded buddy-cop mystery. The second teaser addressed more of the science-fiction side that audiences associate with Green Lantern stories.

May 18, 2026, is the release date of the second teaser, not the premiere date of the series. The first episode was scheduled for August 16, 2026. The official trailer was later revealed at San Diego Comic-Con on July 24, 2026.
