The footage of the young girl with progeria was filmed after the production crew contacted the Progeria Society and were put in touch with the family of Courtney Arciaga, who was a young girl with the disease. She and her family were fans of the series, and were flown from their San Diego home to Vancouver to shoot the scene. See more »


The establishing shot of the recital hall, supposedly in the DC area, is actually the Carnegie Museum of Art in Pittsburgh, PA. See more »


Dr. Joe Ridley: I varied Barnett's treatment. Once I isolated the progeria receptors, I stumbled onto something quite unexpected... these same genes related to the production of myelin.
Scully: The material that insulates neurons in the body.
Dr. Joe Ridley: Yes. You see, myelin is not present in the very young and by reversing the effects of aging, I found, with Barnett, I was able to regulate the production of myelin. Myelin being the material that prohibits you or I from, say, regenerating a new hand if we were to have ours cut ...

Blast from the past
6 September 2006 | by thebigeasy555See all my reviews

An episode from season 1 which gives an insight into Mulder's past and its pretty dark.Earlier in his career Mulder sticking to procedure had a clear chance to shoot a criminal called John Barnett.Mulder didn't want to endanger any other life and didn't take the shot.However Barnett then shot a cop dead.This affects Mulder significantly and struggles to suppress the memory.Barnett is sent down but before he is he threatens Mulder that he will get him.It is believed that Barnett died in prison.Years pass.Mulder starts to receive threatening notes and grows worried that Barnett has seemingly returned from the grave but cannot convince himself this.Barnett is indeed back alive and has the perfect disguise-youth.Its a race to find Barnett before he tries to carry out his threat and kill Mulder.

For me the quality of this episode is augmented by the supporting cast.The actors who play John Barnett,the young John Barnett,Reggie Purdue and Dr Joe Ridley are excellent.It helps hold the episode together and makes it all the more enjoyable
