I actually didn't know this was a thriller, until one day on sky Thriller movie channel screened it....
Gran Torino (2008)
This film stars and is directed by Clint Eastwood; Who plays a recently widowed war-veteran who is diagnosed with cancer. The character Walt is a bitter and very set in his ways. He has strong views about religion and the way men should be. He begins to develop a good rapport with his neighbours through the son + daughter of a Hmong family (a ethnicity from an asian decent).
I will not reveal to much... but basically the film changes the character. What's a thriller without a death right? This film contains false plateau, dramatic Irony which are the classic combination for a thriller.
Unlike Alfred Hitchcocks, "Psycho", "Gran Torino" uses a variety of weapons, for example; guns and a baseball bat. Which is quite normal in modern day thrillers. The use of weapons make us know or judge a character quite easily. Which I would like to take in to consideration when filming our final opening title sequence.
Just like in "stephfather" (2009), props can really help us judge a character quickly.
