After Fogg and his companions have been launched from the paddle-ship, the captain asks; "How are we going to get back?". Yet the paddle-ship has sails.
The ship HAD sails but was dismantled for the construction of the flying machine. No sails are left intact as shown by a wide shot of the ship on day 80.
A guy falls out of train, and Jackie Chan looks to his left while saying "Sorry". This gives impression that the train is moving right. But as the camera pans out, the train is shown moving towards his left.
When Fogg and companions escape the gallery in France where they encountered the men searching for Passepartout and exit through the manhole to the balloon scene, the movie still clearly portrays them as being in France. However, the actual location of the Balloon scene and the palace in the background is Schloss Charlottenburg, a palace in Berlin, Germany.
On the paddle-ship on the Atlantic, the paddles are turning and some of the sails are also unfurled. However if the wind was having any effect it would have to be going faster than the ship. In that case the smoke from the smokestack should be blown forward, in the direction of travel. In fact it is shown going sideways or even backwards; this implies that the sails are actually causing a drag on the ship, slowing it down.
When Passepartout and Inspector Fix are being attacked by the Chained Agent in India, one of the shots show the agent bursting through a wall. The remains of the wall are clearly not clay or sandstone, but instead something along the lines of plasterboard or cardboard.
After Fogg and his companions have been launched from the paddle-ship and start to descend from their initial impetus, a rainbow can be seen below and in front of them. However the sun is to their left; a rainbow cannot be formed in that location - it should be off to their right.
