Continuity mistake: Kimble's been kidnapped and held for ransom. He had nothing with him when he was taken, yet when he leaves the abandoned house with the kidnappers, he has a small suitcase. When they drop him off on the road, he doesn't have it. When, in the epilogue, he's shown walking, he's carrying a different, larger suitcase.
Continuity mistake: Kimble orders coffee and a bowl of chili from the diner's owner, George. But George serves him a glass of water with the chili, and never does bring the coffee. Later, when the sheriff arrives and wants Kimble's dishes to get fingerprints, a cup of coffee mysteriously appears next to the bowl of chili.
