For wrestling die-hards, the recollections by Hulk Hogan of the lead-up to his match with Andre at WrestleMania III are something special. One great detail is his explaining how he wrote out the entire match on a yellow legal pad McMahon gave him when McMahon asked the wrestler how he thought the match should go down. Hogan scripted the entire match — but left how it would end empty for Andre to decide. Andre didn't reveal the ending until during the match, according to Hogan.

In the movie, while Hogan is telling the story, there are shots of yellow legal-pad sheets with handwriting on them. Hehir said that was really Hogan's handwriting of the match.

"That yellow legal pad is crucial to the telling of that story," he said. "But that has been long crumbled and thrown into the trash. Probably the night of the event. So for months I tried to get Hogan to re-create to the best of his recollection what he wrote down."

Hehir interviewed Hogan for the movie in April of last year. He said he finally got the pages from Hogan in the middle of December on the final day they could possibly get it in the movie before handing a finished version over to HBO.

"When we got it you could feel your heart beat opening the envelope," Hehir said. "I told Hogan even if he could write a few lines, we could shoot them really tight. He ended up writing all those pages you see in the shot — two single-spaced pages. And he wrote it as if he was in the moment, so if you freeze-frame it, you can see it says something like, 'Don't let Andre see this.'"

"Any of us could have written those pages and no one would know whose handwriting it was," Hehir continued. "But I just thought it would be a cool wink to people who do know this world that they would recognize Hogan's handwriting."
