Why 'X-Men: Days Of Future Past' Changed The Iconic Look Of The Mutant-Hunting Sentinels
For the film's production designer John Myhre it was important to bring the killer machines to life while also focusing on their look from the comics.
"The first thing I did was say, 'What do the Sentinels look like?' And it's amazing how often they've changed since the 60s and stayed quite often the same," Myhre told Collider.
For example, when the Sentinels first appeared in X-Men #14 back in 1965 they looked more human than robot.
MarvelYet, they maintained their signature look focusing on their purple helmet shape and glowing yellow eyes.
The premise of the movie will see Hugh Jackman's Wolverine character getting sent back in time to prevent the creation of the giant bots.
The 1970's version of the machines stayed true to the robots' look in the comics.
Myhre went in a different direction for the futuristic version of the Sentinels, coming up with an entirely new design.

"They're biomechanical weapons," Myhre told Empire. "We had to come up with what would be the ultimate version that could actually, in principle, stop the X-Men."
To do this Myhre reconsidered both the design of the robots and their ability to attack mutants.
"We started with this idea that they were almost made up of magnetic plates slapped over one another," Myhre added. "The plates could contract or grow, so the Sentinel can be skinny to get through a small space or the plates can open up to become a bigger shape."
This includes shape-shifting parts of their bodies into weapons.
"They have become virtually unstoppable," Myhre said.
