Rope is a film adapted from Patrick Hamiltons 1929 Play which itself was said to be based on grisly Leopard and Loeb case of 1924.
Nathan Leopold and Richard Loeb were upper-class Chicago law students who murdered of a 14 year old Robert 'Bobby' Franks. The duo was motivated to murder Franks by their desire to commit a prefect crime.

For a film to be a thriller you need to know who the antagonist and the protagonist is and from the beginning of Rope we know who the antagonists are. Later on during their dinner we find out who the protagonist is too.
Brandon and Phillip are the antagonist that have all the equipment needed to make a crime and Rupet is the resourceful hero that has no equipment but yet find out what has been happening in the house during that dinner.

Rope falls into the thriller genre as they use suspense almost throughout the film. For example when they want to look at the books in the trunk but the dead body is in there so the audience has been put on suspense because they don't know what they going to do, if they will open the trunk and find the dead body or not. This scene only put the audience on the edge as they are the only people who know what exactly is in there, the characters have no idea so its not really as frightening as it is for the audience watching.

Hitchcock has used invisible cut perfectly fine as they have ended at the same person or item and began exactly where it left off. Hitchcocks claustrophobic strength technique suits the film as the characters are trapped in the room where the coffin is and of course they don't know but for the audience that do know it makes them feel thrilled to be in the same place as where they have witnessed a murder.
