Hollywood stars Patrick Dempsey, Shia LaBeouf and Rosie Huntington-Whiteley are in Milwaukee at the Milwaukee Art Museum shooting scenes for Transformers 3. The museum will be closed during shooting, which will involve a crew of about 150 along with 50 paid extras. The film is scheduled for release next summer. The museum on the Lake Michigan waterfront serves as the city's symbol for tourism. Local officials hope the national exposure will lead to more visitors.
