Shot in 15 days.
Directorial debut of Tony Krantz.
"Iatrogenic illness" is a real term and it does happen, though the statistics quoted in the film and therefore the conclusions drawn from those numbers are questionable.
Joe Manganiello was originally cast in the part of the spiritual exorcist "Friar Lazaro Mate." But he was recast when he had to cut his long hair and shave his beard to reprise his role as "Flash Thompson" in Spider-Man 3 (2007). (NOTE: He did shoot a day on the film and appears briefly in the hallway scene performing a breast augmentation.)
