This is a micro-budget horror film produced by the performers, who used their real names and pretended to be making a documentary within the script, thus giving the project a “cinema verite” or “found footage” feel. Kris Collins starred, wrote, directed and co-produced.
The IMDb score of 3.8 demonstrates that they were not especially successful.
Paranormal investigators Kris, Celina, and their videographer Jay expect the usual scares when they set out on their latest case. But after being mysteriously rerouted to an abandoned house deep in the woods, they find themselves facing a force unlike anything they have encountered before. As the night spirals into chaos, missing crew members and eerie phenomena hint at an ancient, malevolent presence watching their every move.
Damn, was hoping it would be Selina Meyer.
Since that clip is creator-commentary, they’re saying how “Barb did a good job” and “It was just me and Celina up there with Barb, so she wouldn’t be too uncomfortable”, which makes it seem like the naked woman is Barb Thomas (per the IMBD listing of the movie), not Celina Myers.
You may be right. I assumed it was Celina because of the body shape and the fact that Celina was obviously possessed by a demonic spirit in the previous scene, but the point you made seems reasonable. Although the image quality is insufficient for an ID, the ghastly naked apparition appears to have different hair from Celina, and seems to lack Celina’s tattoos. I don’t know what Barb Thomas looks like, and there are no images of her available on the internet, so perhaps the film just cornered the market on obese women.
