Peacemaker Cast Breaks Silence on Season One Finale’s Surprising Cameos
Peacemaker's season finale included an appearance by the Justice League themselves; well just four members: Wonder Woman, Aquaman, Flash, and Superman.
Encased in darkness, the superheroes replicate their DCEU counterparts, but we do see Jason Mamoa and Ezra Miller reprise their titular roles. Showing up late to the action, Peacemaker voices his frustration and Aquaman himself finally addresses rumours of his sexual infatuation with fish, a running joke throughout the show.

Jennifer Holland gave her reaction on the cameos, voicing her excitement on bringing these two actors while, comparing their appearances to Samuel L. Jackson's Nick Fury:
Holland initially, wasn't sure on how fans would react. But, it did show that Peacemaker and the 11th Street Kids still have a place in this world alongside DC's finest.

Steve Agee also voiced his joy in shooting the scene, having been a long-time fan of the squad:

Agee also went into detail on how the segment was filmed, as the suits and figures were included to represent DC's movie characters:
Peacemaker grew in viewership numbers as the season progressed, with ratings for the finale marking a 44% growth from the premiere. The last episode also accounted for the biggest viewership performance for an HBO Max original in one day.
With The Suicide Squad spin-off's major success, Peacemaker has been renewed for a second season and has the talented James Gunn returning to write and direct all 8 episodes.
