Here is a list myself and my group discussed and compiled of all films with a  similar plot line as our film. All of these films follow a psychopath and that is the basis of their plot similar to our thriller.

Perfume: The Story of a Murderer (2006, Constantin Films, Tom Tykwer)
The Silence of the Lambs (1991, Strong Heart/Demme Productions, Jonathan Demme)
Psycho (1960, Shamely Productions, Alfred Hitchcock)
Hannibal (2001, Dino De Laurentiis Company, Ridley Scott)
American Psycho (2000, Edward R. Pressman Productions, Mary Harron)
Henry: Portrait of a Serial Killer (1986, Greycat Films, John McNaughton)
Red Dragon (2002, Dino De Laurentiis Company, Brett Ratner)
Death Proof (2007, Troublemaker Studios, Quentin Tarantino)
Maniac (2012, Canal+, Franck Khalfoun)

The three main films that are the most similar to our film I must admit are...
The Silence of the Lambs, American Psycho and Red Dragon.

When looking at similar plot lines, we looked at films that included things about serial killers that killed their victims in a creative way, as we plan to have our killer have an obsession with being creative when murdering his victims. Therefore, I think the following films are similar:

Perfume: The Story of a Murderer (2006, Constantin Films, Tom Tykwer)
Peeping Tom (1960, Anglo-Amalgamated Film Distributors, Michael Powell)
Sweeney Todd (2007, Parkes/MacDonald Productions, Tim Burton)
Maniac (2012, Canal+, Franck Khalfoun)
Tony (2010, AbbottVision, Gerard Johnson)
Se7en (1995, New Line Cinema, David Fincher)

For location my group discussed and we looked at films that were either in an unknown location, or in one remote location throughout the majority of the movie. In our thriller we have decided that we want to film it in a secluded area like a basement fr example somewhere dark and mysterious, these films are similar in that sense of location:

Sweeney Todd (2007, Parkes/MacDonald Productions, Tim Burton)
Perfume: The Story of a Murderer (2006, Constantin Films, Tom Tykwer)

We wanted the twist in our thriller to be quite unexpected. These films also share the same unexpected twist even if they differ in storyline.

The Killer Inside of Me (2010, Revolution Films, Michael Winterbottom)
Kalifornia (1993, PolyGram Filmed Entertainment, Dominic Sena)
American Psycho (2000, Edward R. Pressman Productions, Mary Harron)
Gone Girl (2014, Regency Enterprises, David Fincher)
