I'm pretty sure I saw the beginning of the film Cellular but not the whole thing. I remember seeing the call and wondering why he goes along with it, and keeps driving but other than that the film is gone to me. I think I can actually remember changing the channel. I'm not saying it was a bad film, just not one I was into watching on that particular day.
Now that I know there's a Porsche Cayenne Turbo in it, for most of the film, I must really check it out. It's pretty rare that they use a Porsche for the main car throughout a movie. They do it sometimes, but that usually means it's a specific Porsche and it has something to do with the character. In this case I don't think that's the case, but it's still sweet to see the Porsche do a lot of driving. Most of those times when the Porsche is important to the character the car scenes are limited, only for added effect, like in Go On. So this film is quite the rarity as far as vehicles are concerned. Not sure if we can catch it on Netflix but it seems like something I may watch on a Sunday, in the rain.
