Why Michael J. Fox felt 'like a whore' on the set of this teen classic

What on earth happened on the set of the 1985 supernatural comedy “Teen Wolf” that made Michael J. Fox feel so dirty?

Well, it was thankfully something very benign.

In his new memoir, “Future Boy,” Fox details the time period he was filming “Back to the Future,” and naturally mentions a few of his other films, including “Teen Wolf.”

“Teen Wolf” was filmed a few months before “Back to the Future,” and looking back, Fox joked in his memoir that the supernatural comedy is not exactly “my magnum opus.”

But he experienced an even stranger feeling while posing for some product placement photos.

"It was already obvious to me that ‘Teen Wolf,’ filmed a few months prior, was not my magnum opus," Fox wrote, per Entertainment Weekly. "One day on the set of that film, the prop guy made me take a few photos holding a chocolate bar so they could show the confectioner who supplied the candy that we had actually used their product in the movie.”

“Covered in yak hair, I told him that I felt like a whore doing this. The prop guy said, 'Well, you are a whore,’” he joked.

“Teen Wolf” was still a hit, but it got completely eclipsed by that other high concept film he starred in that year, “Back to the Future.”

In his memoir, Fox noted that the whole “whore” exchange on the set of “Teen Wolf” was an "especially stark [comparison] to the crew surrounding me on ‘Back to the Future.’”

As he wrote in his memoir, “Back to the Future” “changed everything” for him.

So, why did he take the role in “Teen Wolf” if he wasn’t, as it seems, wowed by the story?

Part of it was simply an easy gig, and the fact it was his first leading role in a film he could do on a break from filming “Family Ties,” the show that made him a star.

Fox wrote in his memoir his agent "seized the moment and sent me the script for a quick, low-budget movie called ‘Teen Wolf.’ They were ready to start filming, and the five-week shoot could easily slide into the production hiatus at ‘Family Ties.’”

The leading role was, by Fox’s own admission “a hackneyed one that required me to wear twenty-five pounds of yak hair,” he thought it would work out since it worked for another TV icon.

He wrote that “the wolf thing had worked for Michael Landon in ‘I Was a Teenage Werewolf.’”

"Teen Wolf" was successful enough to spawn a sequel, starring Jason Bateman, and a TV series of the same name, starring Tyler Posey, Dylan O'Brien, and Tyler Hoechlin.
