This film could have been titled “There Will Be Beef.”
At one point in "Digging up the Marrow," a straight-faced mockumentary about a man who discovers another man who claims to have seen real-life monsters, filmmaker Adam Green ("Hatchet," "Frozen") compares his film-within-the-film to a "found footage film." Kane Hodder, the horror icon and man listening to Green's explanation, bristles: "Found footage, huh? Like that hasn't been done before." That exasperated, knowing wink to viewers is a throw-away gag, but it also says more about Green's ambitions (or lack thereof) than he realizes. "Digging Up the Marrow" is a decent idea, but beyond some fun creature effects, and a surprisingly grounded performance from character actor Ray Wise, the film just sits there. Green, who plays a snotty version of himself, doesn't follow through on any of the ideas that make his film stand out. As a result, "Digging Up the Marrow" just uselessly lies there, like a cat during a heat wave.
"Digging Up the Marrow" begins with an ambitious, but ultimately pointless preface. Real-life horror convention guests, like "Toxic Avenger" director Lloyd Kaufman and "Candyman" star Tony Todd, tell Green about their first experiences with horror films, and why they're drawn to the genre. Other convention attendees then admit that they either believe or want to believe in monsters since many of them sympathize with monsters. After this, Green introduces himself by complaining about having to hype himself up ("I already sound like a douchebag"), and ragging on horror fans to his cameraman. Then Green stops clearing his throat, and gets to his film's subject: out of all of Green's fan mail, the most exciting correspondence he's received came from William Decker (Wise), an eccentric retired Boston police officer who claims to have seen real monsters.
Green then wastes a lot of time establishing Decker as an unreliable character. Decker tells us his story in his own time: he's a loner, divorced, highly imaginative, and also happens to have discovered a portal to a secret world of creatures. We sit and listen and wait for more enlivening details to come because, well, Green is at his mercy, and so are we. This wait-and-see strategy allows Green to back-load his special effects budget into his film's too-little-too-late conclusion, which goes pretty much exactly where you'd expect it to. Until then, "Digging Up the Marrow" is a lot of frantic "Did we see something/can we see something" conversations between Green and Decker.
Half of these conversations are interesting because half are carried by Wise's weirdly measured performance. Wise is probably most well-known for losing his cool in "Twin Peaks," a slew of decent B-movies, and a ton of unbearable SyFy Channel movies. But here, he acts like someone you probably know, maybe your grandpa, or that sketchy guy you see on the subway every morning. He talks to Green as if he's pre-planned his end of their conversation, and simply will not abide any interruptions, not now, nuh uh. In true old man fashion, Deck knows what he knows, and that's all that he knows. Wise perfectly conveys that non-philosophy every time he flails his arms in response to Green's constant questioning.
