Marvel's prop designer reveals some franchise secrets

We love geeking out about the making of our favourite films, so one Marvel Studios' props designer revealing some behind-the-scenes secrets is right up our street.

In an interview in The Mirror, Russell Bobbitt – an industry veteran who has been creating all the bits and bobs of the Marvel Cinematic Universe since Iron Man – has teased some info.

Although he can't say anything about Avengers 4, he did talk about the infamous Infinity Gauntlet that's so important to the plot of Infinity War (having been built up for absolutely ages).

"It's interesting as Thanos is a completely CGI character but we built a real-life gauntlet with an old school blacksmith with an anvil," he said, "a piece made with a method that could have been made in 1700s.

"We used that real Infinity Gauntlet for lighting checks and for Josh Brolin to work with during his performance. Post-production then modelled the CGI version on that designed real Gauntlet."

Not only was the Infinity Gauntlet not made by space dwarves, but Captain America's shield wasn't actually made of vibranium.

In fact, there are multiple shields, with some made from aluminium, some made from fibreglass and others made from hard or soft plastic. There are about 20 to 30 shields per film and they usually last about two or three scenes each.
