Long before Harrison Ford took on the role of Richard Kimbell, David Jansen was portraying the character to perfection from 1962-67. In every episode, people he met in different cities fell into two categories: those who wanted to turn him in, and those who believed in his character and helped him escape.
I never watched the TV version of the show, but I REALLY liked the movie of "The Fugitive" (in spite of some of the painful plot holes). One of the reasons I liked the movie was because the two main characters, who were completely at odds with one another, were BOTH "good guys." You had a compelling "good guy vs. good guy" story, and that is rare.
The Chicago cops, who were on the same side as Gerard, were the "bad guys." They were bad because they were not interested in the higher cause of justice. They were intersted in getting a conviction and catching an escaped convict, but they emphatically were NOT interested in correcting a wrongful conviction or admitting errors in their investigation, even errors made in good faith. And part of what made the story good was that Gerard wasn't interested in any of this either, but in order to catch Kimble, Gerard HAD TO revisit the facts of the case so that he could figure out what Kimble's next move might be. After revisiting the facts, Gerard found out that Kimble probably had been wrongly convicted.
At the end of the movie, Kimble is in Gerard's custody, and Kimble knows he has an ally. But Kimble is not a free man, he is at risk of conviction of a number of other serious offenses (escape, assault, theft, etc.) and it is unclear whether he will ever be cleared of his wife's murder.
It is interesting that some of the evidence of Kimble's innocence was available to him at his trial. (Other pieces of evidence, like the phone records that eventually convinced Gerard, were not available.) Would it be a plausible story that Kimble's conviction might stand, since the jury heard most of his evidence and didn't buy it?
