Male or Female Audiences

I have been trying to decide who should be the main protagonist of my opening sequence in order to attract the right gender to my film. I have carried out some research using www.boxofficemojo.com and I have found that typical psychological thrillers have both male and female audiences. The fast paced action of a thriller tends to attracts the male audiences, where as the psychological elements tend to sttract females. To widen my distribution and gain bigger audiences, I have decided to include the psychological elements to attract female audiences aswell as males. The protagonist (especially when they are a serial killer) is prodimantley male, and because this seems to be successful with audience (e.g. Hanibal using a male protagonist making $165,092,268 at boxoffice), I will use a male protagonist. I believe this will benefit the dominance and intensity of the sequence, as males are sterotypically seen to be more agressive and dominating over women - the serial killer with appear more frightening.
