As production wound down, the set of Stephen King’s “Graveyard Shift” received some national visitors Friday.

A crew from “48 Hours,” the CBS news magazine, came to the set of the movie, which was shot Friday at a Hermon warehouse and the Brewer Armory, to film a segment for a program on fears and phobias. The “48 Hours” show will air around Halloween, about the same time “Graveyard Shift” is due to be released.

“This film involves fears and rats, and one guy on the crew is blood-phobic,” said “48 Hours” correspondent Phil Jones. “This segment is aimed at how movies play on those phobias, even unintentionally sometimes. It’s fascinating how the movie industry deals with these things and how they limit themselves.”

Jones stressed that “48 Hours” was addressing the problem of phobias very seriously.

Jones, producer Denise Shriner, and a two-person film crew arrived in Bangor Thursday night, and planned to leave Friday night.

Many from the “Graveyard Shift” crew are also beginning to leave the Bangor area. The main film crew finished Thursday, and the secondary crew should be done in two to three days, according to Richard Scott, the film’s unit publicist.

During June and July, the movie has been shot at a mill in Harmony, the bar Johnny Mack’s and the Armory in Brewer, a warehouse in Hermon and the abandoned Bangor Waterworks.

The story of “Graveyard Shift” begins with the reopening of an abandoned textile mill. As factory workers labor during the dead of night, they discover that they are in the presence of an unimaginable horror.
