He is probably best known for his role as Mr. Eko on the ABC series Lost, but Akinnuoye-Agbaje also did fantastic work as Simon on the HBO show Oz. He was Heavy Duty in G.I. Joe: The Rise of the Cobra, and he recently played supporting roles in Killer Elite and the prequel to The Thing. His other credits over the last decade include Pompeii, The Bourne Identity, Faster, Unstoppable, and Get Rich or Die Tryin'.
He recently shot a supporting role as Dave Duerson in the NFL drama Concussion, now he's on board to reunite with that film's star, Will Smith, in Suicide Squad. Neither the actor's reps nor Warner Bros. have officially commented, but according to The Wrap, Agbaje is set to play Croc, aka Waylon Jones, a sewer-dwelling villain who has been wrasslin' Batman since the early 1980s but has never made the jump to a live-action film.
Given just how many DC characters are already set to appear in Suicide Squad, it's unlikely that Croc has a major part to play in the story; this is probably more of a cameo, perhaps in a cell at Arkham Asylum. Still, since Warners is doubling down on the whole shared universe thing, the character could show up in any number of DC movies down the line.
Akinnuoye-Agbaje joins a jam-packed ensemble that includes Smith as Deadshot, Margot Robbie as Harley Quinn, Jared Leto as the Joker, Jai Courtney as Captain Boomerang, Cara Delevingne as Enchantress, Joel Kinnaman as Rick Flag, Viola Davis as Amanda Waller, and Jay Hernandez as El Diablo.
Scott Eastwood (son of Clint) also recently joined the cast, and The Wrap reports he's rumored to be playing a love-interest for Wonder Woman (Gal Gadot), who as far as anybody knows doesn't actually show up in this movie. Karen Fukuhara is playing a mystery role, while Jesse Eisenberg might just reprise his Batman v Superman role as Lex Luthor for a Suicide Squad appearance. Ben Affleck's Batman could also pop in, but he might simply be alluded to.
Writer-director David Ayer is currently preparing to kick off production on Suicide Squad in April for an August 5, 2016 release date. Suicide Squad, occasionally known as Task Force X, is a team of a convicted supervillains given a shot at redemption by participating in dangerous top-secret missions that are extremely likely to get them all killed.
