Although fans and entertainment sites are closely following the effort to replace Tom Hardy in David Ayer's Suicide Squad, stars Will Smith and Margot Robbie maintain the delay in finding a new Rick Flag isn't as big of a deal as some seem to think.

"We've still got to get it right," Smith, who'll play Deadshot, told USA Today while he and Robbie were promoting their new film Focus.

Hardy left the Warner Bros. project last month, reportedly because his role was diminished when Smith and Jared Leto were cast. The studio immediately turned Jake Gyllenhaal, who passed on the DC Comics-inspired movie. With production set to start in April, rumors have swirled about Joel Edgerton and Jon Bernthal, but nothing has been announced.

"This happens all the time," said Robbie, who'll play Harley Quinn. "People act like, 'Oh my god, the movie must be ending!' It's just the deal with movies. A lot of the characters haven't been portrayed before so it's a pretty big undertaking." She added, "And it's a big undertaking for the people who are going to play the characters who have been played, like the Joker. It's big shoes to fill."

According to Smith, one of the reasons the Flag role has yet to be filled is because of the holidays. "[Ayer] turned the screenplay in before Christmas," he said. "What happens is Hollywood shuts down. But he was still working and he wanted to [start shooting] April 13th. So it takes a couple weeks to gear back up at the top of the year and people have taken [other] movies. He's moving really quickly."

Suicide Squad -- which also stars Jai Courtney as Boomerang, Cara Delevingne and likely Viola Davis as Amanda Waller -- is scheduled to burst onto screens Aug. 5, 2016.
