''Yesterday Was a Lie'' is a 2009 science-fictional FilmNoir homage by director/writer James Kerwin, starring Kipleigh Brown as Hoyle, and featuring former ''Series/{{Star Trek|Deep Space Nine}}'' actress Chase Masterson as a mysterious and significant -- but nameless -- lounge singer who becomes Hoyle's ally.

Hoyle is a hard-drinking private detective(?) searching for a missing scientist and a missing Nazi notebook, and instead uncovering mysteries about the the nature of reality and time. Quantum mechanics, Jungian philosophy and {{fanservice}} all feature heavily.

The movie spawned a short-lived web series in 2011.

!!The film contains examples of the following:

* AbsoluteCleavage: Masterson's (Singer's) dress for most of the film. Both Hoyle and Singer in the art museum.
* BadassLongCoat: Brown (Hoyle) wears one as part of her HardboiledDetective gear.
* BareYourMidriff: Singer's shirt for the latter portion of the film. Hoyle's white suit in the jazz club (briefly).
* DeliberatelyMonochrome
* DieselPunk
* FilmNoir
* HardboiledDetective
* HotChickInABadassSuit: Hoyle wears one through the middle portion of the film.
* LingerieScene: Hoyle's shirt is removed in order to dress a gunshot wound, leaving her wearing just a bra in the rain.
* MeaningfulName:
** Hoyle's cat is named "Schrödinger" after one of the founders of quantum mechanics, who described a famous thought experiment called "Schrödinger's cat".
** Hoyle may be a veiled reference to astronomer Sir Fred Hoyle; in one scene, a character reads "October the First Is Too Late," Fred Hoyle's book which outlines his concept of non-linear time and a reality "clerk," also referenced in the film.
* MsFanservice: Hoyle and Singer would both qualify as fanservice.
* OperaGloves: Singer's dress in the jazz club when she sings "Yesterday Was a Lie."
* ScienceFiction
* ShowSomeLeg: Hoyle persuades a male physics student to spill secrets to her by sitting in front of him in a miniskirt and crossing her legs.
