Happy Face Murders is a 1999 American made-for-television crime drama film directed by Brian Trenchard-Smith.

It was shot in 21 days[1] and is one of director Brian Trenchard-Smith's favourite films.

[2] Lorraine Petrovich (Ann-Margret) frames her abusive lover killing a young intellectually disabled girl by creating details of the murder from clues she picks up from Detective Jennifer Powell (Marg Helgenberger).

Powell works the case with law doctoral student Dylan McCarthy (Henry Thomas), whom she repeatedly calls "Doc", despite McCarthy not actually being a doctor yet.

After implicating herself, resulting in her jail sentence, she then recants her testimony but no one believes her, until clues surface from the real killer, who leaves messages that he is still out there, has killed before, and will kill again, signing his victims with Happy Faces.
