Andrew Garfield believes his Spider-Man costume was designed to make him feel "irritated".

The 28-year-old actor has revealed the pains of starring as the superhero in the highly anticipated film The Amazing Spider-Man.

He says wearing a tight leotard was one of the biggest challenges of the role.

"It's made of something that is designed to make you irritated," he told talk show host Ellen DeGeneres.

"I don't know what that material name is but that's the description underneath."

Andrew adds that he had to work out like a "crazy person" to fit into the suit. He needed help to get into shape.

"It was a life change," he said of the strict exercise regime. "I get frustrated with those Men's Health magazines. It's like in five minutes you'll be as fit a as fiddle if you just follow those three simple steps and only eat cucumbers but this was hard work. I wouldn't be able to do it without someone."

The Social Network star went on to say he felt naked in the suit as he wears nothing underneath. He joked he was also worried the suit was too tight.

"Knowing that your keaster is being shot from many different angles is uncomfortable," he laughed.

Ellen then offered the actor advice on how to handle paparazzi as the movie is set to send his star rising. She handed Andrew a blonde mullet wig, moustache and sunglasses, suggesting it would be a good disguise.

Andrew put on the gear saying, "I feel like I should do a German accent, I feel like I should be a German man."

The new Spider-Man film is set to hit theatres worldwide from July and also stars Andrew's real-life girlfriend Emma Stone.
