'Avengers' Director Joss Whedon: Earth's Mightiest... Giggler?

Joss Whedon

Like many of you, I've been waiting for years for "The Avengers" to assemble on the big screen. I've seen myself cheering, hooting, hollering, holding my breath, even laughing at the hopefully frequent Whedonisms littered throughout the movie.

But giggling? Can't say I've pictured that — which makes it all the more hilarious that Joss Whedon, the man who directed the Marvel Studios team-up, apparently giggled his way through the entire shoot.

The Los Angeles Times spoke with Loki actor Tom Hiddleston, who had a whole lot to say about Joss' giggling habit.

"Joss gets really excited, I love hearing him giggle from behind the monitor," Hiddleston said. "It's almost like he's hiding behind his own giggles … he's always giggling about something."

So what's he giggling about? According to the occasional Asgardian super villain, Whedon's unstoppable laughter stems largely from his ability to tap into the dark side of "The Avengers" — namely, Loki and his mischievous ways.

"He has this intermittently generous and supportive side as a director," said the actor, "but I also think as an artist he has a really dark sense of humor. He kept telling me how much fun he had writing Loki. He steps inside the villains in a way that he doesn't with the heroes. "

That's not the only way Whedon gets involved with his films, said Hiddleston, who went on to describe an unnecessary stunt the director put himself through while on the "Avengers" set.

"There was one scene where Robert Downey Jr. has to fall to [the] floor and we were trying to work out how to do the film and trying to work out how extreme it should be and Joss came over and said, ‘I think it should be like this,' and he just hurled himself at the floor headfirst," said Hiddleston. "I was like, ‘Buddy, are you OK? We could pad you up before you do that!' But he went up in my estimation after that."
