This is one of the best series pilots Irwin Allen ever produced. After years of watching the color antics of Smith and the robot, this episode comes as a real shock. It's fast paced, well acted and has great music. Truly a 10+ episode.
I need to point out, however, that this episodes list of guest stars is incorrect. You have Byron Morrow as Gen. Squires and Hoke Howell as Rogers listed. However, they are not in this episode, they are in The Time Merchant in season 3. You do have Hal Torey listed as a General, which is correct, but he is the only one.
Also, Irwin Allen is listed as The Voice of the President. This is also wrong, since Ford Rainey, who plays the president, was not dubbed over. It's his own voice. The only voice over Irwin did was announcing the president: "Ladies and gentlemen...the president of the United States!"
