The director of "The Breakfast Club" and "Ferris Bueller's Day Off" died of a heart attack Thursday during a walk in Manhattan. The 59-year-old Hughes was in New York to visit family.
In addition to family and friends, colleagues such as Vince Vaughn, Ben Stein and Matthew Broderick gathered Tuesday at the Wenban Funeral Home in Lake Forest for Hughes' memorial service.
Stein, who played Ferris Bueller's teacher, was one of the speakers who paid tribute to Hughes.
He called the service "very touching" and said there was "a lot of crying."
After the service, the mourners gathered in a procession to a Lake Forest cemetery, where Hughes was to be laid to rest.
