Joss Whedon warns: 'Avengers: Age of Ultron' is going to mess up Seoul

No one ever said saving the day was pretty.

In fact, protecting the world from megalomaniac villains can get downright destructive. So when Joss Whedon and the Avengers: Age of Ultron crew arrived in Seoul, South Korea, to begin filming the latest franchise installment, the director wanted to give residents a heads up that things were about to get very, very messy.

In the following video, Whedon apologizes in advance for street closures, traffic, and any other headaches his big-budget action sequences shot in the area will inevitably cause.

“We are going to mess it up a bit and inconvenience some people for a few days and I apologize for that,” he says. “I know what that’s like. I live in Los Angeles. It happens to me all the time and it’s not fun. I hope that it will be worth it.”

It’s a friendly gesture; bonus points for talking up how much he adores the city:

The Avengers: Age of Ultron reteams Robert Downey Jr., Chris Hemsworth, Chris Evans, Scarlett Johansson and Mark Ruffalo. James Spader plays big baddie Ultron.

The film hits theaters May 1, 2015.
