Researching thriller movies

As using the genre horror was confusing people about what my film would contain, i decided to look into the thriller genre. I found this definition on wikipedia:

"Thrillers are characterised by fast pacing, frequent action....."
"The genre is a fascinatingly flexible form that can undermine audience complacency through a dramatic rendering of psychological, social, familial and political tensions and encourages sheltered but sensation-hungry audiences, in Hitchcock's phrase, "to put their toe in cold water of fear to see what it is like."

I watched some thriller trailers to see what they contained, so i knew what to and what not to put in mine. Some that i looked at:

• Psycho
• Red Dragon
• Leon
• Memento
  
  Alfred Hitchcock's 1960 movie 'psycho' is still one the most remember able thriller movies of all time. It could also be classed as a romance thriller because of the love story between Lila Crane and Sam Loomis.
  
  
  
  After watching lots of already existing thriller movies i decided my movie was definitely more a thriller than a horror. Looking back at my questionnaire on question 8, when asking people if they thought thriller and romance went well together all 20 said yes. This means my target audience will have expanded as more people would want to watch my movie. Therefore i am now classing my movie as a thriller romance which is already a genre in its own.

John Patterson 2006, said:

"Thrillers provide such a rich literacy feast. There are all kinds. the legal thriller, spy thriller, action adventure thriller, medical thriller, police thriller, romantic thriller, historical thriller, political thriller, religious thriller, high tech thriller, military thriller. The list goes on and on with new variations constantly being invented. In fact, this openness to expansion is one of the genres most enduring characteristics. But what gives the variety of thrillers common ground is its intensity of emotions they create, particularly those apprehension and exhilaration of excitement and breathlessness, all designed to generate that all important thrill. By definition if a thriller doesn't thrill, it's not done it's job"
