She has just been revealed as the 'most physically perfect woman', according to Ancient Greek ratios of what defines such a coveted title.

And Scarlett Johansson was exhibiting this 'Golden Ratio' coup as she got to work filming scenes for Captain America: Civil War in Atlanta, Georgia on Wednesday.

The 30-year-old beauty wasn't dressed in her famous Black Widow all-in-one leather catsuit for the scene, but she still managed to flaunt her famous figure in a sleeveless curve-hugging black dress.

The perfect superhero: Scarlett Johansson looked sensational in a figure-hugging black dress while filming scenes for the upcoming Captain America movie in Atlanta, Georgia on Wednesday

She looked trim and toned while on the set, following the birth of her daughter Rose Dorothy with husband Romain Dauriac in September, and has no doubt been hitting the gym hard in preparation for her all-action, high-octane role.

Scarlett has previously revealed that she does a lot of her own stunts while in the role, and over the years has built up her tough training while honing her figure with a combination of fighting training, Wushu (a Chinese sport), and rigorous interval drills.

The usually-blonde star wore a long, curly-haired wig in the deep red shade for her character, covering up her current peroxide pixie crop.

In-between takes, the petite Hollywood beauty kept herself comfortable in a pair of flat slide-on shoes, but she was later seen emerging in towering heels, as well as being covered in a classic black trench coat.

Glad to be back? The actress looked content to be back with her co-star on the set of the third Captain America sequel

Chris Evans - Captain America himself - was also present for the scene, which put to bed rumours that they were filming the protagonist's funeral.

However, a funeral was certainly being filmed earlier this week, leaving fans of the Marvel franchise wondering whose death was being mourned.

It was recently reported by Just Jared that the third film in the Captain America series picks up where Avengers: Age of Ultron - which was released in April - left off, as Steve Rogers leads the new team of Avengers in their continued efforts to protect the human race.

With their last heroic efforts once again causing collateral damage, there is soon political pressure to install a system of accountability and create a governing body to decide when the world should enlist the services of the super team.

The new status quo fractures the Avengers while they try to protect the world from a new villain.

Fans were delighted that the film will prove to be an Avengers reunion of sorts after the full cast was finally revealed.

Chris, of course, returns as iconic Super Hero character Steve Rogers/Captain America along with Robert Downey Jr. as Tony Stark/Iron Man.

Covered-up: The actress was also seen later on in heels while having covered up in a black trench coat as filming commenced

Jeremy Renner is set to return as Hawkeye while the likes of Sebastian Stan, Anthony Mackie, Paul Bettany and Don Cheadle will also star in the action flick, which is slated for release in May 2016.

Elizabeth Olsen stars as Age Of Ultron newbie Scarlet Witch with Frank Grillo as Brock Rumlow/Crossbones and William Hurt as General Thaddeus 'Thunderbolt' Ross.

Martin Freeman was announced as the latest addition to the movie recently, but the character he is playing is still unknown.

According to the gossip site, Paul Rudd will make his first appearance as Scott Lang/Ant-Man, while Daniel Brühl - who rose to fame in Ladies in Lavendar - as supervillain Baron Zemo.

Keeping the fans guessing: Marvel devotees had been concerned about the funeral scene, many of them thinking it was for Captain America himself, but Chris Evans was alive and well on the set on Wednesday

Suited up: Chris looked incredibly handsomed in his sharp three-piece black suit while filming scenes as the film's protagonist

A recent casting notice for the Disney action movie, set to be called Captain America: Civil War, includes a detailed synopsis of the planned movie.

'Billionaire Tony Stark is pitted against Captain America aka Steve Rogers in an ethical face-off over the U.S. government's Superhuman Registration Act, which requires all superpowered individuals register their powers and report to S.H.I.E.L.D.' it states.

So far, Scarlett has appeared as Black Widow/Natasha Romanoff in several Marvel films: The Avengers and The Avengers: Age Of Ultron, as well as Iron Man 2 and Captain America: The Winter Soldier.

Filming begun on the all-action flick last week and is expected to run until August.
