The Rambo star recently revealed he'd given up hopes of playing Poe in the project - and now he fears he'll never complete work on the project because he fears the wrath of the writer and poet's fans.
Stallone has invested years on the script, writing multiple drafts, but he tells America's GQ magazine, "He (Poe) was like Rocky - he was just incredibly misunderstood... I don't know if I could ever live up to the hype.
"Poe fanatics - I mean in an intellectual sense - they would tear me to pieces. My take is very simple - he's a misunderstood artist."
