Not exactly a series of books, but I would like to see Mick Foley's autobiography Have A Nice Day: A Tale Of Blood & Sweatsocks be made into a biodrama, with elements of Foley Is Good added in to make a more complete story.
I'd start it in much the same way the book starts, with him losing his ear in a match against Van Vader in Germany. Then go back to his childhood in Long Island, New York. His hitch hiking to MSG to see Superfly Jimmy Snuka. His bad date which lead to him making his backyard wrestling movie, "The Loved One". Then go on to his training to become a wrestler, his struggle to make it in the business, his meeting his wife Colette, and his eventual rise to superstardom. Then end the film with either (a) his Hell In A Cell match against Triple H, or (b) his Fatal Four Way Elimination Match at Wrestlemania.
Another book written by Mick Foley I would love to see be made into a movie (at least an animated movie), is his children's book Mick Foley's Christmas Chaos. Granted, some of the humour value has deminished, especially for younger fans, as many of the wrestlers mentioned in the book have since moved on with their careers, or even passed away. Still, I'd love to see that book receive the "How The Grinch Stole Christmas" cartoon treatment.
