Dr. Alvin Kurtzweil
(Martin Landau)He is a former friend of Mulder's father, and now makes a living writing books about various conspiracy theories and the new world order. The books are titled "The Four Horsemen Of The Global Domination Conspiracy" and "Countdown to the Apocalypse". He is a gynaecologist, OB-GYN. He reads magazines like "National Gynecology & Obstetrics" and "Obstetrics & Gynecology". "I'm a character who gives Mulder a lot of information - to either fill my books or maybe save mankind," says Landau. "It's an interesting relationship that develops in a surprising way." "We needed someone who could appear to be crazy and credible at the same time," says Carter. "And Martin Landau brought to it a certain gravity because of the actor he is." Landau was intrigued by the role because it offered the chance to portray a complex, multi-layered character. "If you know my work over the years, you'll see that the more complicated a character is, the better I am," Landau says. "I like duplicity. I like characters who are losers, but don't give up. Kurtzweil has a checkered past and what he's saying sounds a little loony, and yet it's valid in the context of the piece." He gets killed by Well-Manicured Man.
(Armin Mueller-Stahl)As the elegant and imposing leader of The Syndicate, German-born Academy Award nominee Armin Mueller-Stahl became the first member of this clandestine organization to actually be given a name, Conrad Strughold. "He is an evil person," Mueller-Stahl says. "He is trying to create and command over an awful new world." Mueller-Stahl's biggest scene comes in an emergency meeting of The Syndicate to determine a course of action to stop Agent Mulder from his investigation. Due to the strong leadership qualities he had to bring to Strughold and the amount of information he had to deliver, Mueller-Stahl admits, "It was the most difficult scene I ever played."
Assistant Director Jana Cassidy
(Blythe Danner)She is a no-nonsense bureau official who reviews Mulder and Scully's work in a formal FBI hearing. "She's putting the screws to Mulder and Scully, and enjoying it," says Danner. "The FBI is trying to shift blame, and they're the scapegoats."
Dr. Ben Bronschweig
(Jeffrey DeMunn)He is overseeing the scientific aspects of the global conspiracy. He is attacked when the creature wakes and was left in the cave and buried (still) alive by his co-workers. "He's a scientist through and through," DeMunn notes. "He's motivated by what he can discover and what he can learn. He's fascinated by his subject."
Special Agent Darius Michaud
(Terry O'Quinn)He is brought in early in the story to locate and deactivate the bomb planted in a Dallas office building. He fails, but is seems that he came to the place to die, because he doesn't even try to deactivate the bomb. He just sits in front of it and get blown up in really nice way. "I think the film will be a similar experience to the series, but much fuller," O'Quinn notes. "And I think it will be more intense in probably every conceivable way."
(Glenne Headly)She is a barmaid in a downscale Washington D.C. Casey's bar where she listens to a somber Mulder spilling his guts about his life. She seems to be very neat.
(Lucas Black)He is a young boy who falls into a cave and makes an incredible discovery when he finds the human skull. Then he is attacked by the black oil and left in the cave by his three boyfriends. He gets out (yet probably dead) in quarantine and then is blown into pieces by the explosion in Dallas building.
