PCW: Was it hard to make the actual body of the cab look like a cop car?

Carras: The idea of changing the cab to a cop car came from Josh, because he knows that most cabs are actually former cop cars. Once they sell them, they already have the cage separating the front from the backseat, so it's easier to remodel them into cabs.

Comen: If you look at some cabs, they say "Police Interceptor" on the back -- obviously just a cop car that's out of service, so it was the path of least resistance for us that worked for the production. And it was ultimately what they wanted, so it worked all the way around.

Carras: One of the early notes we got was "does there have to be so many cabs in a row? Can we change some of them?" So we said, "Sure, we'll change one of them to a cop car." And we managed to find an Accord in the footage somewhere, and it happened to be stationary enough to work.

PCW: What kind of software did your team use for the effects?
