This is the Halloween Police, anyone that doesn't know Bruce Campbell as Ash from Army of Darkness is the third or "other character" must turn in your Halloween card. Line forms to the left.

That would be the character I'd vote for but I'd imagine they'd have to get Bruce's persmission to use his likeness & if he says no it could end up like the Beetlejuice character from Grandin Road or the Frankenstein character they had last year. It will resemble the character but it won't look enough like Ash to know it's Ash because it won't look like Bruce Campbell just like Beetlejuice doesn't look like the Michael Keaton Beetlejuice we all know & love & the Frankenstein doesn't look like Karloff.
Using someone's likeness costs a pretty penny, especially when it's an iconic image like Karloff's Frankenstein or even Marilyn Monroe. I doubt Spirit will pick Ash for that reason alone.
Chucky would probably be their choice since there's a new Chucky movie coming out soon so even though he won't be fresh in the memories, they've got a new likeness to work with that the studios will probably want to promote.
