In any case, Idris Elba is too big of a Hollywood star for The Suicide Squad team to let go of, so it shouldn’t take long for them to find someone else for him to play.
Bronze Tiger is a reasonable choice, since like Deadshot, he was one of the original members of the first Task Force X that debuted in the late 1980s.
But he’s just one of numerous potential candidates on the table, with plenty of others, like Blockbuster and Multiplex, just waiting to be adapted for the big screen.
So now Deadshot is off the table for The Suicide Squad, although if there’s the possibility of Will Smith playing the character again, then naturally Floyd Lawton is still alive in the DC Extended Universe, and is likely either still custody at Belle Reve or managed to escape imprisonment and resume his mercenary duties.
