With production on Suicide Squad starting in just a few weeks, David Ayer’s unlikely comic book adaptation has begun filling in the final pieces of its seemingly endless cast. Scott Eastwood, Adewale Akinnuoye-Agbaje and boxer Raymond Olubowale are the latest additions to ensemble, taking on the roles of Steve Trevor, Killer Croc and King Shark.

All of this news came about in a somewhat roundabout fashion. eTalk was the first to report that Eastwood (yes, the son of Clint) was joining the cast, but Latino Review was the first to report that he would be playing Steve Trevor. News of Olubowale’s casting broke at the Toronto Sun, but Latino Review once again got the scoop that he would be taking on King Shark. Meanwhile, we can credit The Wrap with the Akinnuoye-Agbaje news.

Since this casting is being revealed so late in the game, it’s unlikely that any of these characters will play particularly large roles in Suicide Squad. In fact, it wouldn’t surprise us if they are being inserted just so they can be set up to appear in future DC universe movies. After all, Killer Croc is a major Batman villain who has never been seen on the big screen before, so it would make sense for him to tussle with the Dark Knight in a future movie.

This is most definitely true for Eastwood’s Steve Trevor, who is a character associated with Wonder Woman. Originally, he was the soldier who first discovered the island of the Amazons and brought Wonder Woman back home. In recent years, he has evolved into her on-again, off-again love interest and government liaison charged with helping her adjust to life in our world. Recent comics have put him in charge of a top secret government agency called A.R.G.U.S., which will probably get name-checked at some point in Suicide Squad.

And King Shark ... he’s just a big shark monster. And he looks cool. So why not?

The casting itself, like the rest of Suicide Squad’s eclectic ensemble, is certainly interesting. This kind of role is nothing new for Akinnuoye-Agbaje, who excels at portraying characters who exude raw, physical menace (and he’s played a comic book villain before in Thor: The Dark World). The casting that has us really interested is Eastwood, an actor who has been trying to break out for a few years now. Pulling off a tough guy role like this will go a long way to propelling him into his own career and will force internet articles like this to stop always introducing him as the son of a living legend.

Suicide Squad is set to open in theaters on August 5, 2016.
