Breaking Dawn doesn't come out for another three weeks, but the Robert Pattinson mayhem has already started.

The 25-year-old British actor is currently in the middle of a mini European tour to promote The Twilight Saga: Breaking Dawn - Part 1.

On Thursday, Pattinson was joined by co-star Ashley Greene, as the two arrived in Brussels. The film's other stars, including Pattinson's real-life girlfriend Kristen Stewart, were no shows.

The Twilight Saga: Breaking Dawn - Part 1 is the second to last film of the series, based on the popular novels by Stephenie Meyer. The novel Breaking Dawn was broken down into two films, both directed by Bill Condon. Part 2 arrives in theaters on Nov. 16, 2012.

Since the release of the first Twilight film in 2008, the franchise has grossed millions worldwide. Eclipse released in 2010, grossed more than $698 million at the box office worldwide.

To celebrate the new film, Summit Entertainment launched a new interactive Web site, The Twilight Time Capsule, on Oct. 14. The studio is also holding multiple screenings of the first three films across the country, in anticipation of the arrival of Breaking Dawn - Part 1.
