The director released a video on Thursday in which he apologizes to Korean citizens for the inconvenience the shoot will cause.
"I'm really grateful and excited to be filming in your city," Whedon says. "We are going to mess it up a bit and inconvenience some people for a few days, and I apologize for that."
Seoul has given the director unprecedented access to the city for the Avengers shoot. The Mapo Bridge will be entirely shut down from 6 a.m. to 5:30 p.m. on March 30. Other streets and parts of the city will also be closed to the public.
"I know what it's like, I live in Los Angeles," Whedon continues. "It happens to me all the time, and it's not fun."
"I hope that it will be worth it. We love this movie, we love your city," the director says. "Having the two of them together will show the city to the world in a light that I don't think it's ever been shown... For us to showcase it...is a real privilege."
Avengers: Age of Ultron features South Korean actress Kim Soo-Hyun as a doctor and scientist friend of Tony Stark (Robert Downey Jr.). About twenty minutes of the movie will take place in South Korea.
Filming begins in Seoul on March 30 and ends April 7. Avengers: Age of Ultron will be released on May 1, 2015.
