David Ayer Fine Tuning Suicide Squad Script

Even though the cameras are set to roll for Suicide Squad, director David Ayer is still hard at work on the film's script.

In a Tweet posted earlier today, Ayer wrote that he is still-fine tuning the screenplay to his super heroic take on The Dirty Dozen.

Working on the script again. Need the best and smoothest draft possible. #writing #SuicideSquad

Currently in Toronto for principle photography, Ayer and some Squad member including Jared Leto (The Joker) are preparing to film their first scenes later this month. It was reported earlier this week that the movie's main villain won't be the Joker after all, but a lesser-known character named Antiphon. Good thing he's reportedly bringing in DC heavyweight Deathstroke to do his dirty work.

Suicide Squad casts the DC Universe's worst villains for a government-sponsored special ops group for the deadliest of missions. It is schedule to hit theaters on August 5th, 2016.
