Siphayo (English: Dismay) is a 2016 Philippine erotic thriller independent film directed by Joel Lamangan, and starring Luis Alandy, Joem Bascon, and Nathalie Hart.

According to director Joel Lamangan, Nathalie Hart was initially hesitant for the lead role when told that she is required to do full-frontal nudity for the film, but said that "she did not have second thoughts doing it (...) It was a project she simply could not pass up.

[3] She claimed that her recent breast enlargement surgery was crucial for the film.

The following day, after filming a sex scene with co-star Luis Alandy, she said she "went in the bathroom and cried", and almost prompted to abandon the project as she felt she was doing pornography.

[6][7][8] Joem Bascon confirmed in a separate interview that Hart performed her nude scenes genuinely and without the use of nipple tapes.
