According to Latino-Review, they’ve learned that Scott Eastwood will make a cameo appearance as Steve Trevor in Suicide Squad.
In “The New 52”, he’s part of A.R.G.U.S. and plays a key role in helping Wonder Woman acclimate to her new surroundings. They also have a brief romance which obviously didn’t end particularly well what with Diana now being in a relationship with Superman! Regardless, Eastwood playing must be playing the character here in order to set up a bigger role in Wonder Woman, and you have to wonder just how much of a part both A.R.G.U.S. and Amanda Waller will play in that and Justice League.
The site adds that Raymond Olubowale will have a minor role as a member of Waller’s security team and that he’ll also be providing motion capture in order to bring King Shark to life!
