'Ferris Bueller’s Day Off' Star Alan Ruck on Movie's 30 Years of Popularity

— -- Alan Ruck said he still gets stopped in the street for his role in the 1986 classic “Ferris Bueller’s Day Off,” a testament he says to the movie’s enduring popularity.

“Ben Stein, who played our teacher...he said that, ‘This movie doesn’t have a mean bone in its body,' and that’s true,’” Ruck said today on “Good Morning America.” “It’s really a movie about a guy who’s very successful at life helping his friend who’s got some trouble, who’s having a bad day, and that’s really all the movie is about.”

In the movie, Ruck, now 59, played Cameron Frye, the friend in need, to Matthew Broderick’s Ferris Bueller.

“Everybody wants to be the guy who has the world wired and has the world at his fingertips, but most of us are the ones who have problems and need a little help,” Ruck said of the movie’s lasting appeal.

The movie’s plot line of Bueller skipping school and convincing Frye to go along with him, including driving in his dad’s Ferrari, took place in Chicago. To celebrate the film’s 30th anniversary, the city is hosting a three-day “Ferris Fest” this weekend.

ABC News’ Nick Watt got a first look at “Ferris Fest,” including talking to some of the movie’s other stars. Watch the video above to see Watt’s Bueller-like adventures in Chicago.
