Henry: Chân Dung Kẻ Giết Người Hàng Loạt

Michael Rooker said he was working as a janitor when he auditioned for the part of Henry, and went to the audition in his janitor uniform. He got the part, and continued to wear his uniform throughout the film shoot. He only had one jacket, though, and he took it off before he "killed" anyone, so he wouldn't get blood on it.

During the home invasion scene, the boy can be seen breathing after being killed.

Before the film begins the following can be read: "This film is a fictional dramatization of certain events. 'Henry' is not intended to be an accurate portrayal of a true story. The film is based partly on confessions of a person named Henry, many of which he later recanted. As to Otis and Betty, the film is fictional."

The film has had a long and complex relationship with the BBFC. In 1990, distributor Electric Pictures submitted it for classification with 38 seconds already removed (the pan across the hotel room and into the bathroom, revealing the semi-naked woman on the toilet with a broken bottle stuck in her mouth). Electric Pictures had performed this edit themselves without the approval of director John McNaughton because they feared it was such an extreme image so early in the film, it would turn the board against them. The film was classified 18 for theatrical release in April 1991, but only if 24 seconds were cut from the family massacre scene (primarily involving the shots where Otis gropes the mother's breasts both prior to killing her and after she is dead). Total time cut from the film: 62 seconds.
