A flyer and a logo

I want to promote the concept of a new TV Quiz Show with a poster / flyer to be sent by email to production companies, supported by a logo.
The concept is a Quiz Show building towards the "Final Question", which is the working title, where one player walks away with everything, and the other, nothing.
So I want to convey - in a family friendly but striking way - the tension and drama as both players prepare to finish each other off. Perhaps getting the feel of a Showdown or a Duel. This town ain't big enough for the both of us, etc.
Maybe one player with their hand hovering over the button for their final answer, while the other player holds their hands in front of their face as they can hardly bear to look.
Or check out branding of other successful quiz programmes like The Chase, Pointless and Who Wants to be a Millionnaire. The latter has the best fit, in terms of being dramatic.
But other ideas appreciated...!
