Beneath the Darkness (2011), an American thriller. Vaughn Ely (Dennis Quaid) is a former high school football star, now mortician of the small town of Smithville, Texas by day and psychopath by night. Four high school friends, Travis, Danny, Brian, and his girlfriend Abby (Tony Oller, Devon Werkheiser, Stephen Ford, and Aimee Teegarden) discover Bad Things in Vaughn's home while snooping for no good reason and one of them is killed. After that it is a battle of wills then like a battle battle as the three survivors try to prove to a disbelieving sheriff and parents that Vaughn murdered their friend (rather than dying in an accident in Vaughn's home) and also prove another Bad Thing and Vaughn tries to stop them.
It feels like an afterschool special type film or maybe something filmed for LIfetime, not bad production values but not great either. There are a few tense scenes, some low-level scares, Dennis Quaid is at times kind of over the top evil and one time actually breaks the fourth wall but everyone else plays it kind of seriously to very seriously. Aimee Teegarden as Abby did a good job especially among the rest of the cast, though some of the secondary cast weren't good actors. One in particular was kind of terrible.
Dennis Quaid is the best part of the film. I see some people call the movie a black comedy and his scenes were, though the rest of the film definitely plays it straight. He came off at times like he was in a different movie, as scenes without him are written and played with such earnestness. A few of his lines were actually kind of funny.
There is a plot thread with Travis who as a kid maybe saw a ghost (shown in a flashback) and later decides he understands some Big Thing when I guess he thinks back to it. I absolutely did not understand any of this, either what it had to do with the rest of the film or just in general.
Wikipedia says Smithville, Texas is a real place and the movie was filmed there in 20 days.
