You can get a more romantic view of a pro wrestler character in "Better Late" (still available from Phaze Books), which tells the tale of the reunion between a wrestler and a woman who used to work with him as a publicist. Rourke's role in The Wrestler doesn't delve much into the erotic (though he does have a stripper girlfriend played by Marisa Tomei), but of course he was famous back in the day for his performance opposite the ravishing Kim Basinger in 1986's ultra-steamy Nine 1/2 Weeks.
If you want an amazing movie experience, I recommend The Wrestler, and if you want something a little hotter, I definitely recommend "Better Late" from Phaze Books!
