“REUNITED bruce and arthur. love u and miss u Ben. WB studio tours just explored the backlot alright. busted on set all great things coming AQUAMAN 2 all my aloha j,” Momoa wrote in the caption for a series of photos he shared in which the two pose together while goofing around.

This is followed by a video in which Momoa is seen speaking to a group riding a tram on the studio tour at the Warner Bros. lot in Los Angeles.

He then walks into the trailer, where Affeck is sitting. “Sorry bro,” Momoa tells Affleck while laughing uproariously, ending the video by exclaiming, “Whoops!”
