Andrew Garfield's Most Crucial Spidey Suit Upgrade: The Zipper

Andrew Garfield endeared himself to Spider-Man fans — and showed he’s got the sense of humor to play perhaps the world’s goofiest superhero — when he talked about how difficult it was to urinate in costume during an Amazing Spider-Man promotional stop on The Daily Show in 2012.

He even brought a visual aid in the form of a photo of himself in Spidey’s blue and red suit, standing at a urinal attempting to relieve himself.

"Spandex isn’t fun," he told host Jon Stewart while complaining about how difficult it proved to do the deed.

So he had to fix that little costume shortcoming for the filming of The Amazing Spider-Man 2, right?

"Yes, that was figured out," Garfield told Yahoo Movies at the movie’s New York press day. "I got a zipper. I made sure that was in my contract, that we had a fly, because I don’t like other people having to take me to the bathroom. That’s rubbish."

It was as simple at that?

"Yep just add the zipper!" Garfield laughed.

The XYZ factor wasn’t the only upgrade to Spidey’s suit for the second installment of Marc Webb’s rebooted series.

The eyes on Spidey’s new costume are significantly larger (“It’s a lot more visual range,” stuntman William Spencer told Yahoo Movies) and the shades of blue and red appear to shine brighter. He got new footwear, too, with soles adapted from Vans’ skate shoes.

Also, the intricate spider web design on the crime fighter’s chest employed screen printing to “create precision webbing,” according to an MTV News interview with the film’s costume designer, Deborah Lynn Scott.

Of course, the costume will only take a superhero movie so far. (Just ask that dapper Green Lantern.)

Garfield admitted that what also needed improving after the first Amazing Spider-Man, which was a box office hit with a $262 million U.S. take (and $752 million worldwide) but left audiences and critics mixed, was the substance, like story and tone.

"The script in the first movie felt a little bit like a patchwork quilt with lots of different people making it," Garfield said. "And we had to work really hard to find one voice, one through-line on each day of filming, to make sure that there was logic to it."

The actor credited newcomer Spider-Man scribes Alex Kurtzman, Roberto Orci, and Jeff Pinkner, who count TV projects like Lost, Alias and Fringe among their collaborations.

"On this movie, that was the biggest thing, we got great screenwriters from the outset, and they fashioned a story that made such logical progression, and held beautiful themes, and is jam-packed with great action and a love story."

It all clearly matters dearly for Garfield, who admits Spider-Man follows him into sleep mode while the series is in production.

"When I’m playing the character, I’m dreaming in Spider-Man all the time," he said. "I can’t help it. It just affects your subconscious. That’s the best idea, because that’s where all the creativity comes from, it comes from the back of the mind, the darker recesses of the mind."

Let’s just hope he doesn’t have to worry about using that zipper while he sleeps.
