When Mulder is being tested by Kritschgau for psychic abilities, Mulder jokingly asks "Who ya gonna call?" The test is similar to the one performed on a co-ed in Ghostbusters by Bill Murray 's character Dr. Venkman. Michael Ensign, who appears in this episode as Dr. Barnes, is the hotel manager in Ghostbusters. See more »


In the scene were Mulder writes a message on Skinner's hand, he writes it along the bottom, starting near the baby finger. The next time you see Skinner walking, he reviews Mulder's message, but it is now written on an angle starting at the middle of the hand, leading to the thumb. See more »

Good Season Opener
11 March 2006 | by See all my reviews

Following on from Biogenesis (Season 6 Finale), Scully desperately tries to discover the secrets of the spaceship beached on the Ivory Coast in West Africa, while Mulder lies in hospital with Skinner and a returning character hoping that they'll find a way to save him.

This mythology episode is a personal favourite of mine because it continues with an interesting topic, over how we came to exist and whether our ancestors were aliens or not.

The only let-down is Diana Fowley (played by Mimi Rogers), a character that I've never really been fond of, who goes around arguing about Mulder being her one true love and that she'll take care of him.

6/10 - Maybe not the best X-Files opener, but 'The Sixth Extinction' will manage to get your attention.
