Funeral at Fifty-Mile - S1-E22
Continuity mistake: When Jessica walks from the house to the barn at the end, she is wearing knee high brown boots. By the time she reaches the barn they have been replaced with court shoes.
Continuity mistake: When Mike and his friend escape from the helicopters in El Salvador, Mike's hair, clothes and camera are wet just before they pass in the river. They were not wet in the previous shot. (00:04:10)
Brother's Keeper (1 & 2) - S1-E1
Visible crew/equipment: In the scene where Crockett and Tubbs first meet at the deal, after the cops bust the deal too early, Tubbs steals Crockett's boat to get away. As he's driving the boat away, you see a second person kneeling down in the back of the boat, most likely a crew member. Very obvious.
