didn't know about the big-screen adaptation of James Dashner's best-selling novel.

According to the cast, The Scorch Trials was even more physically demanding and involved

even more running than the first movie. So, when Ki Hong Lee, who plays Minho, was

running up sand dunes, he suffered a minor fracture to one of his knees.

But that wasn't the only injury he sustained on set. He also cut himself several times

after he asked for a real knife instead of using a blunt one for a scene where he flipped

a knife and caught it. As for Kaya Scodelario, who plays Teresa,

although she avoided injury while filming The Maze Runner, she wasn't so lucky on The

Scorch Trials where she had back and knee problems from all the running.

And being barefoot for part of the movie proved its own hazard as Scodelario ran into a bolt

sticking that was up out of the set floor and pulled off her toenail!

The main cast took part in a boot camp before The Scorch Trials began filming.

However, whereas training for the first movie included learning survival skills and camping

overnight in the wooded Louisiana location used for the Glade, The Scorch Trials boot

camp involved running 2 to 3 miles a day in Albuquerque's mile-high altitude and practising

stunts such as a long slide through a closing door and a leap-into-mid-air-kick.

Most of the movie's sand dune scenes were filmed at Pajarito Dunes, west of Albuquerque

in New Mexico. The design team removed footprints and vehicle

tracks from the dunes by sweeping with rakes and used a low-hovering helicopter as a giant

fan to create a swirling effect in the sand.

After a hard day filming The Scorch Trials, many of the cast spent the evenings hanging

out together, playing Mario Kart and cooking. Kaya Scodelario made Brazilian dishes and

reckoned she was the best in the kitchen because she's inherited her Brazilian mother's cooking

gene. Dylan O'Brien's specialities were chicken

parmesan and breaded chicken cutlets, while Dexter Darden, who plays Frypan, loved to

grill and also made a mean macaroni and cheese as well as fried chicken.

The movie's party sequence was shot over two days at an 8,500-square-foot mansion known

as The Castle in downtown Albuquerque. The Castle was built over two years from 2006

and was the home of late jewellery designer Gertrude Zachary.

During filming, the walls of the mansion were covered in dark green wallpaper aged with

mildew and staining to give this quite new building the feel of a grand mansion past

its glory days. The design team also added hundreds of candles

melted down into mounds, and VHS tape that was pulled out to use as streamers.

The dark tunnels, storm drains and diversion channels under the University of New Mexico

Hospital in Albuquerque proved the perfect place to film scenes set beneath the desolate

landscape of the Scorch.

The sequences in Jorge's lair were filmed on sets constructed at Albuquerque Studios

and at the vacant railyard complex south of downtown Albuquerque, where movies including

The Avengers and Terminator: Salvation, and TV show Breaking Bad have also filmed.

The design of where the scavengers live in the lair was inspired by the look of Kowloon

Walled City in Hong Kong, a now-demolished stacked building structure where people lived

in very cramped conditions. Lots of the objects used to dress the set

of Jorge's penthouse were bits of metal and junk furniture found in salvage and recycling

yards.
