Back in the day, if you couldn't get into R-rated movies and your household didn't have a VCR, it was a big deal whenever anything horror-related would rear its head on TV - no matter how tepid it was. I was so hard-up for horror as a kid, I would even get stoked whenever Fantasy Island would take a turn towards the scary (which it often did, as in those episodes when Mr. Rourke would lock horns with Satan) and I thrilled to the episode of The Brady Bunch where the Bradys went to Hawaii and it appeared as though they had fallen victim to a cursed tiki idol.
But when earnest school teacher turned bumbling superhero Ralph Hinkley (William Katt) crossed paths with the eponymous entity of The Greatest American Hero episode, "The Beast In The Black" (originally aired on December 9th, 1981) that was heaven for me. GAH was my favorite series at the time and they were doing a horror episode to boot - how cool was that?
...It's so haunted, in fact, that it even has a wheelchair that moves by itself and careens down a staircase, as in the then-recent supernatural shocker The Changeling (1980).
Scouting out the location ahead of the arrival of his students, Ralph and his cohort in crime fighting, FBI agent Bill Maxwell (Robert Culp), start to see what this old house is made of. Wearing his alien-made super suit, Ralph approaches a brick wall and is able to see past the wall to what looks like a portal into another dimension. Invisible to Bill's eyes, a woman (Christine Belford) sits in a parlor in front of a fireplace.
...Turning when she senses Ralph's eyes on her.
As Sheila Redman, a woman who died years ago in the house, the look of actress Christine Belford here reminds me of Karen Black in Burnt Offerings (1976) - specifically as Black's character looked at the end of that movie, with her brown eyes having turned an icy shade of blue.
Believing the woman is silently imploring him for help, Ralph is able to use to suit to pass intangibly through the brick wall, into this fourth dimensional space. Instead of standing in the parlor he was just peering into, he's first wandering through a vast black space.
And whatever it is that those eyes belong to (the episode is vague as to what the Beast actually is - apparently some kind of watchdog from beyond), it makes lunch out of Ralph. In describing the omnivorous creature featured in "The Crate" episode of Creepshow (1982), Stephen King referred to it as like the Tasmanian Devil of Looney Tunes fame but that more accurately relates to "The Beast In The Black" in that, like that whirling cartoon tsunami of teeth and claws, the Beast flashes in and out of sight with subliminal speed. Ralph doesn't even get a chance to fight back, the poor bastard.
Making it out of the fourth dimension and to the local hospital, Ralph's body is seen to be covered in vicious welts. As a kid, this struck me as pretty hardcore. I mean, Superman never got torn up like this. It's common today to see heroes getting knocked around and bloodied but at the time it was a novel to see a super powered character be so vulnerable to attack. It's also interesting that, unlike most fictional heroes, Ralph isn't required to go back for a win in order to retain his heroic posture. Most heroes would've been honor-bound to not let anyone or anything get the best of them but in "The Beast In The Black" (written by Juanita Bartlett), Ralph doesn't let his ego put him back in harm's way. He got his ass handed to him but there's so sense of pride drawing him back to even the score. He only returns to the house in order to get his students out before the house can harm them.
The rest of the episode is almost totally Beast-free, dealing with the machinations of the ghost to inhabit the body of Bill Maxwell after he briefly dies thanks to the lethal one-two combo of a brass chandelier and gravity.
Sheila possesses Bill, and apparently will be content to live a new life as a man rather than be destroyed when the demolition crews bring the house down.
Culp does a fine job playing Bill as inhabited by Sheila, but the possession angle can't help but feel so-so after the ferocity of the Beast's attack (and to have Culp speaking in Belford's dubbed voice is unmistakably silly as well). The Beast makes an encore appearance in the climax, tearing Ralph another new one as he has to bring Bill/Sheila back into that fourth dimensional parlor in order to get Sheila out of Bill's body for good. As he does so, the Beast is chomping at his heels all the way.
The Greatest American Hero struggled throughout its three season run to find a balance between the more realistic treatment of its characters and their world that creator Stephen J. Cannell strived for and the more sci-fi, creature-orientated program that the network felt would draw in kids. Usually those later shows were the weakest of the series' run, pushing the series towards infantile territory (not because of the fantasy elements themselves but because of how poorly they were handled), but "The Beast In The Black" was an exception. The episode may not have had a sustained sense of terror, or much logic (why Ralph turns to a psychic to locate Bill when the suit already gives him psychic abilities - which he uses in this same story! - is unexplained), but as directed by experienced TV vet Arnold Laven, "The Beast In The Black" did have a little bite to it.
