Harrison Ford damaged some ligaments in his leg during the filming of the scenes in the woods. He refused to take surgery until the end of filming so that his character would keep the limp. The limp can be seen in any subsequent scene where Richard Kimble is running.
The scene where Kimble is running through the St. Patrick's Day parade was not scripted. This was a later addition by Andrew Davis. Davis, a native of the city, really wanted to capture the parade and was granted permission from the mayor's office to film the day of the parade. The entire sequence was shot with a hand-held steady cam. Without rehearsal, Ford and Jones just went out into the crowd and did their thing, with camera operators running around trying to keep up. Ford observed that since his character was keeping a low profile, it meant he himself didn't stand out much and lasted several minutes in the crowd before being recognized.
