Upon meeting Frank at the restaurant, Lucie says she's happy that he's not "Fat, with long black hair and greasy skin full of acne" which, whilst not flattering, would be an apt description of Joe Spinell's Frank, in the original.
The movie features the song "Goodbye Horses," by Q. Lazzarus. The song was also featured in Le silence des agneaux (1991), another movie about a serial killer who skinned people and had issues with his mother.
We don't see Frank's face until 12 minutes into the film.
Like the original film, this remake was banished in Germany (§ 131 StGB, Glorification of violence). The banishment was lifted in February 2020.
