American Flyers (1985)

Synopsis
It takes a fierce three-day bicycle race up in the mountains to reunite two formerly feuding brothers in this film written by Steve Tesich, the creator of another cycle movie, 1979's Breaking Away. This film will please the cycling lovers out there, as it includes actual footage taken from the famous Coors International Bicycle Classic, held in the Colorado Rockies. The plot revolves around the suspicion that one of the two brothers -- either the pragmatic sports doctor Marcus (Kevin Costner) or the impudent, driven David (David Marshall Grant) -- is likely afflicted with an inherited tendency toward cerebral aneurysms. ~ All Movie Guide
