When Joker is transporting the explosives on the cart, a portion of the bottom rack is visible and empty. Soon after he reaches the destination and takes off the cloth that was obscuring the view earlier. This reveals the bottom rack is filled with 2 or more large boxes.
At 6:54 when the Joker escapes from Arkham Asylum, he grabs a rock, ties it to a makeshift rope, throws it over the Arkham fence, catches the exhaust pipe of a passing truck, he's pulled over the fence, lands on the cab of the truck, and pulls himself in.
His clothes are completely intact and unruffled despite the clearly visible Concertina wire he would have been dragged across when he hit the top of the fence.
While Bruce is walking thru the casino before sitting down at the jokers table he is seen carrying a handful of blue chips, after sitting down and betting with the joker, Bruce's chips are changed from blue to red.
