ABC filmed this original Stephen King mini-series movie at Thornewood Castle in Tacoma, Washington. Restoration, construction and filming for the movie took six months in 2000. The fictional Rose Red Mansion in the film was located at 9th & Madison in Downtown Seattle - in reality this location is a Bridge, crossing the I-5 corridor leading to St. James Cathedral. The road does not dead end.
I've never heard Glenn Miller play out of a flower before.
The group goes to visit "Rose Red" on Memorial Day weekend, which is at the end of May. The shots taken outside during the movie show the leaves all off of the trees and all over the ground in autumn colors, and there is a football game on TV, suggesting that it is more like October.
It takes 8 minutes and 30 seconds for the opening credits to play out.
