Interesting web page about this film
http://www.badmovieplanet.com/3btheater/d/thedeadlytower.html
Despite the URL, the writer praises the film (in a way) and provides an interesting recap along with info about the differences from the real-life event (which actually led to a couple lawsuits).
I thought this was one of the best TV films I've seen. Russell is chillingly effective.
