Kill Bill
A classic which has already been given some love by one group turning WCS into a hyped version that is at least visually awesome. I've carried the flag here for years on the potential of this theme- And if done right, could be well into the top 20.
Stern, JJ, and others have the resources to do this pin real justice with its own complete design from the ground up. Not likely from Stern in the near future though (see below) This would be a great choice for Chicago Pinball, however.

Deadpool- A good choice for a themed pin with endless possibilities. The Walking Dead breaks Stern squeaky- clean Movie/TV -theme image since 2007's Family Guy,and Sopranos before that, so who knows? Ironically, FG TWD, GOT and Sopranos are all TV themes, not movie based, so they haven't stepped out of their self- made movie theme boundaries -just yet.
