Industrialist François Delambre is called late at night by his sister-in-law, Helene Delambre, who tells him that she has just killed her husband, André. Reluctant at first, she eventually explains to the police that André invented a matter transportation apparatus and, while experimenting on himself, a fly entered the chamber during the matter transference.
This movie contains 17 potentially triggering events.
i believe the other comments are referring to the 1986 film - as far as i could tell the 1958 film (which this page is for) had no vomit in it (but please correct me if i'm wrong)
Debatable. In the original Vincent Price movie the actor who turns into the fly realizes he must destroy himself since he can't be turned back and no one can know of his experiment. His wife helps him destroy himself and later it is deemed a suicide.
