Thrillers are one of the finest genres of movies because they get the blood pumping. But one of the most intriguing aspects to a thriller is when claustrophobia is brought into it, when things take place in just the one location. And when the plot is all too realistic, that's when things start to get interesting. This movie takes the idea of numbers being the enemy and turns it into a hostage situation, trapping a TV star inside his own studio while on the air.
