In the casino, Lola wins big. We see the roulette wheel stop after the second turn she takes on 20 black. The wheel is actually stopped. Yet, as Lola cashes out and we see everyone staring at her at the cashier's counter, the roulette wheel is still turning
At the end of the first run, Manni and Lola rob a supermarket. At the end of the third run, when Lola scans the intersection for Manni, the same supermarket is closed and dark. The filmmakers were unable to secure permission to close down the streets for filming, so the scene was filmed just after dawn on a Sunday morning to avoid traffic.
In Part 1, Lola leaves the bank and looks to her right. The shot from this side then shows Lola facing in this direction with a young woman approaching in the background (i.e. Lola's left). The next shot (from the front) has an old woman appear from Lola's left.
When Lola is almost hit by the white delivery truck and she stands staring towards the casino, the birthmark near her lips is on the left side of her face. In all other shots it is on the right side of her face.
As Manni goes to rob the supermarket the first time, the gun is poked into his trousers near his left hip. When he actually goes to enter the supermarket, he draws the gun from the waistband of his trousers on his right hip.
(at around 50 mins) She is running underneath the bridge, and into the tunnel. Far ahead of her, you see two girls doing flips on both sides in the tunnel. It switches views, and then you are looking at her from the front as she is running, and you never see the two girls again.
In each of the three stories, Lola runs alongside an ambulance. The patient in the ambulance is the bank guard that was having chest pains (visible in the second story) and not someone that was only injured in one of the stories.
