The made for TV thriller "Pursuit" has some interest in not only is it based on a Michael Crichton novel (written under a pseudonym), but that Michael Crichton directed it, making his directorial debut. But there is additional interest to be found here. What will strike many modern day viewers is that despite the subject matter, the tone of the movie is significantly restrained. There isn't a swift pace or a feeling that things are going to really fall apart at any second. Though that may not sound like the right tone, it actually is convincing; we see that the government agents are well trained and professional, so they of course are conditioned not to panic. The movie also works well because of its short length (74 minutes) - there's no padding on display here, and the story moves briskly as a result. The only real flaw the movie has is that it doesn't hide the conspiracy very well - most viewers will have a reasonable guess as to what is being planned long before the government agents find out. But even though you will probably guess what is happening early on, the movie remains very effective.
