One shot is supposedly happening in an American city, but it's shot somewhere in Brussels, where they discuss people hiding, then you got a transition shot where now they are supposed to be thousands of km away with said people hiding, and the second shot is filmed in the building across the street.

Many other shots were also combination of places that I knew extremely well, which really was funny at times because once you locate everything it makes the whole situation much more comedic.

"Oddball" was filmed in an Australian town I grew up in. There was a chase scene that combined and compressed multiple locations. In one particular scene you are looking at an extra with a backdrop of part of the main street, but the location he is looking at (supposedly directly across the road) is actually about 1/2km away.
