Look for a DVD or tape of "Tokyo Olympiad", which has some excellent footage of the 10K, which was definitely an exciting race.
In that last lap, the leaders were passing lapped runners and, as Mills and Clarke approached one group, it appears to me that Clarke more or less leaned against Mills to force him outside, so that Clarke wouldn't have been hopelessly boxed in. A moment later, Gammoudi suddenly burst between Mills and Clarke, through a gap that must have been 6 inches wide, and suddenly was in the lead by 5 m, with Clarke and Mills in pursuit. Mills dropped back, but suddeny began an all-out sprint... and won!
Tokyo Olympiad was meant for general viewing and, for me, there is too much time spent showing fan reactions, etc., yet the few minutes devoted to showing the 10K shows what modern TV producers could do with judicious editing.
There is fabulous coverage of Bob Hayes, the marathon, and LJ, too!
