A Los Angeles SWAT team raids a syndicate congregating big narcotics deal that leads to the arrest of the local high profile drug lord named Hades.  In transporting Hades into federal custody, massive alien ships suddenly loom over the city, beginning a merciless extraterrestrial invasion that forces the close knit SWAT team, Hades, and a handful of low on the totem poll federal agents to take shelter at an inmate detention center housing dangerous criminals as everyone outside, fighting for their very lives on the streets of an ablaze metropolis, are swarmed and killed by tentacle spearing, blood sucking aliens.  Running low on ammo, cut off from any kind of rescue, and aware that an attack on them is imminent, the survivors must band together to plan their continuous survival and understand what the aliens want from them before being raided for their blood.

“Independence Day” meets “Assault on Precinct 13” in the blood marauding mayhem of the alien invasion action film “Attack of the Unknown” from writer-director Brandon Slagle (“House on Manson,” “The Dawn”) based off a story by producers Michael and Sonny Mahal of the Mahal Empire production company. The American made, Los Angeles and Las Vegas shot Sci-Fi embattled entanglement labors an intensive visual effects heavy bombardment that bares an unbiblical similarity of the David versus Goliath parable.  Instead of using stones and a slingshot to bring the formidable giant down, gunfire and hand-to-hand combat serve as the nearly useless weaponry of choice against these spacemen, with a slight inspiration of H.R. Giger’s biochemical flare, searching for the junkie’s high of medicinal hemoglobin.  Alongside the Mahal Empire, the company behind the artistry of supernatural-sins, “Art of the Dead,” Spicy Ramen Productions (“Murder Van”), FilmCore (“Clownado”), and Blain-Y-Bootleg Films also stick their producing tentacles into the narrative that entails expropriation of human blood by otherworldly beings.

“Attack of the Unknown” reunites “Art of the Dead’s” Richard Grieco and Tara Reid once again in a non-scene sharing feature, but, this time around, Grieco lands the lead role of Vernon, a long-in-the-tooth cop going through a brutal divorce, going through cancer, and must be the person to save during the invasion…wait, what? Yes, forget the women, children, and possible any other last hope for mankind, Vernon, through the eyes of his SWAT brethren, becomes early on the favorite for survival, but only later into the story does the fact of Vernon’s fatalistic, cancerous blood is the cure for dominion dominance, something that should have been noted when Vernon is labeled as must live. Grieco’s austere soul for Vernon disposes a man without a care or is unpredictable and while the role is overall solid, Grieco is a bit theatrical with the performance. On the short end of the stick is Tara Reid whose barely in a folklore tale told by Hades as a severely brief conclusion on why these malevolent space invaders have landed on planet Earth. Former “Hellraiser: Revelations'” cenobite, Jolene Andersen, and typecast bad guy, “Strangeland’s” Robert LaSardo, without an alternative, had the most intrigue without having a lick of depth with their characters. Andersen is the only female SWAT member, Hannah, with an unexplained connection between her and Vernon other than being colleagues, but Hannah is a bit of a Jane of all trades able to hold her own in a humbling kind of way, making her more likable. On the other hand, the mysterious temperament challenges us to figure out what LaSardo kind of person is Hades; obviously named after the lord of Hell, the drug kingpin isn’t devilish in the least and has the tendency to be more of a stubborn and angst tween. The cast list is huge but the main players involved rounding out the cast list is Douglas Tait, Robert Donovan, Paul Gunn, Mouine Omari, Clay Trimble, Gerardo de Pablos, King Jeff, and, not forgetting to mention as Featured Dancer #1, adult actress Tasha Reign.

Slagle has to reign over and rein in the slew of competing talents and the story’s first act of an indeterminate direction. When the narrative finally settles upon the alien encircled detention center with the survivors’ back against the wall, a harried subplot with two, nearly off the clock San Fernando cops encountering a crashed ship in the desert on the outskirts of town is pushed aside; instead of a smaller, parallel story alongside the SWAT’s predicament, the two cop encounter becomes a bookend story that feels sorely out of place and sheepishly wrapped up. Another out of place aspect, an unfillable character arc within the core story, is with an out of element survivor, a vlogger from Texas, who is the only unqualified defender against an attack and supposed to be on this tangent of earning his “got your back” badge (anyone from Texas, the Alamo state, should know a thing or two about a last stand), but by the time the vlogger musters the courage to shoot back at the bloodsucking tentacles during an elevator escape, the moment is way too late and way too underwhelming to make an impact, leaving his presence wasted amongst a motley crew of rough and tough officers and criminals. Luckily, the Mahal production has plenty of capital to go around to render a bolstering blend of practical and visual effects that tags “Attack of the Unknown” as Slagle’s Michael Bay attempt of a Sci-Fi action film. The visual effect composites are verisimilar in comparison to big budget Hollywood and the practical work, whether be with the fleeting gruesome deaths (ripping off the crown of the head scene was pretty nasty), the alien spacesuits, and the alien’s classic bug eyes and small mouth, harped back on a throwback science fiction alien attack sans the ray gun trope.

For an indie production, “Attack of the Unknown” has a palpable core story with promising visuals that has invaded all major VOD platforms this past August courtesy of Gravitas Ventures. The A/V qualities will not be reviewed due to the digital screener provided, but just to comment on the rigors of budget films, the depth perception issues in the composited effects and the sounds effects not always necessarily syncing properly with the action (i.e. explosions), cold cocks us back down a peg that “Attack of the Unknown” is an indie film. The music score is provided by Scott Glasgow (“Hatchet III”) and the shots are provided by Michael Su, who I thought garnished really neat scenes with smoke and brilliant light. Bottom line, “Attack of the Unknown” just ekes out being entertaining enough but the space vampire’s ground assault traverses a rocky road of dry performances and unfocused bearings that cultivates earnest dramatics progressing into one ginormous space ship-sized cliché.
