you probably didn’t know about the second Avengers team-up in the Marvel Cinematic Universe.

There are five different versions of Captain America’s shield which are used for filming.

Chris Evans, who plays Captain America, prefers to use the lightest version of the shield,

which is made of biscuit foam, so it doesn’t interfere with his acting.

However, that particular shield isn’t very durable unlike the soft rubber shield which

is more hard-wearing but heavier.

Andy Serkis was cast as arms dealer Ulysses Klaw after the movie’s executive producer

Jeremy Latcham saw a fan’s mock-up of Serkis as Klaue online!

To bring the Hulk and Ultron to life, Mark Ruffalo and James Spader worked closely with

Andy Serkis’s performance capture company, The Imaginarium Studios.

So that Ruffalo had a real sense of the Hulk’s size, weights and inhibitors were put on his

body. And to create the Hulk’s roar on set, they

used a sound system and pitch-modulated Ruffalo’s voice.

According to Ruffalo, the technology for capturing the Hulk’s performance had improved since

filming The Avengers, so this time they could capture his facial and body movements at the

same time, instead of separately, which really helped him bring the Hulk to life.

To bring Scarlet Witch’s powers to the big screen, writer-director Joss Whedon was not

only inspired by images from the comic books, but also by how dancers move.

So, Elizabeth Olsen, who plays Scarlet Witch, worked with dancer and movement coach Jenny

White to create fluid hand and arm movements to bring her character’s powers to visual

life on screen and really get her physicality right.

Black Widow’s new fighting batons were inspired by Escrima Sticks, which are used in traditional

Filipino Martial Arts. However, unlike traditional Escrima Sticks,

Black Widow’s batons are charged so she can deliver a jolt of power when she hits

an opponent.

The search for Baron von Strucker’s stronghold began a year before production started.

The filmmakers wanted an impressive-looking building with a cinematic setting in a region

little seen on screen, so the location scouts spent two months visiting potential historical

sites in Europe. In the end, Fort Bard, a 19th-century fortified

complex in north-west Italy’s Aosta Valley, was used as Strucker’s Hydra Research Base

in the fictional Eastern European setting of Sokovia.

The Hulkbuster sequence was filmed over two weeks in the Central Business District of

Johannesburg in South Africa. The shoot involved flying helicopters, crashing

cars and exploding huge pyrotechnics in the city.

Black Widow’s vision was filmed at Tring Park School For The Performing Arts, which

is located in Hertfordshire, England, and specialises in dance.

The scenes featured a number of the school’s ballet students practising in its dance studio.

Former pupils of the school include Star Wars: The Force Awakens star Daisy Ridley and Downton

Abbey actress Jessica Brown Findlay.

Although the Avengers Tower is located in New York City, the massive set for the Tower’s

interior was created by the movie’s production designer Charles Wood at Shepperton Studios

in the UK. Scenes in the Tower feature heavily in the

film so, to give Joss Whedon plenty of variety for filming, Wood and his team designed a

huge set with different interconnected levels and multiple areas including laboratories,

lounges, and locker rooms. In fact, the Avengers Tower is the biggest

set built for a Marvel movie so far.

To film Captain America’s chase scene with a speeding truck, Seoul’s Mapo Bridge, which

is a large multi-lane two-way bridge that crosses the Han River in South Korea, was

shut down completely. Prior to shooting the sequence on the bridge,

the movie’s crew rehearsed the stunts needed on an unopened motorway nearby.

The Avengers’ Quinjet was redesigned to give it a more militaristic appearance, including

a pared-down, more functional-looking interior. As for the Quinjet’s canopy, that was inspired

by the look of helicopter cockpits, so it has glass both in front and below, which gives

a real sense of speed when it’s flying.

The movie’s epic final battle scene was shot on location in both Italy’s Aosta Valley

region and in London, England! Hendon Police College, which is the main training

centre for London’s Metropolitan Police, was used for filming as it had an outdoor

space big enough to double as war-torn Sokovia and accommodate the whole production for three

weeks as well as being secure from the prying camera lenses of the paparazzi.

The movie’s production designer built a church on the site and the filmmakers used

drones to capture multiple angles during the shoot.

Director Joss Whedon has said that filming in that church was “some of the best visceral

comic book stuff” he’s ever shot.
