Angela Martin (soap actress Marj Dusay) hires Jonathan Fletcher (Kerwin Mathews, the dauntless hero in Columbia's classic "The 7th Voyage of Sinbad") and his assistant Sajid Rowe (Cal Bellini, an ethnic 1960s John Stamos) to investigate the haunted mansion that she's just inherited.
Another reviewer referred to this short film (actually a television pilot) as "not really that interesting" and "only a footnote" in the world of horror. I think that sums it up nicely. While this did not turn into a "Dead of Night" television series, it seems to be closely linked to "Dark Shadows".
The writer is Sam Hall (who did 315 episodes of "Dark Shadows") and the director is Lela Swift (who did 585 episodes of "Dark Shadows", as well as 589 episodes of "Ryan's Hope"). We even have great music from Bob Cobert, a Dan Curtis regular, setting the tone. This idea never really went away so much as just became repackaged.
There's some questionable things about the show... like a mummy coffin with hinges? And they have very Broadwayesque stages and acting styles, not unlike soap operas or a high school musical. Personally, I was turned off my this over-the-top approach. But really, if you have a chance to see this, I'd say go for it... once. There's nothing particularly special about this film and it's easily forgettable.
