What do you get when you combine a sentient, artificially intelligent subway train (starring Emma Clarke, the voice of the London Underground and Keanu Reeves) with Speed and Titanic? It turns out you get "Sentient Subway," a hilarious Hollywood movie pitch that needs a bit of work on its title. However, having heard this whole pitch, I'm going to go out on a limb and say... it ain't half bad. We'd take a ride on it. In fact, we're all for sentient every mode of transportation: bicycles, cars, roller skates, scooters. Just not buses. Those things are filthy.
