“I was found early,” Macchio said. “I got picked very early on, but it was like one of those test offers where you’re not yet. I remember walking past and seeing Charlie Sheen hanging out outside [producer] Jerry Weintraub’s bungalow, thinking, ‘What is Charlie doing here?’ “
Here too? “Nic Cage, I think, and Robert Downey Jr.”
“Robert Downey Jr. also did the workshop for the part I did in The Outsiders.”

So even if the possibility was small, we could have gotten a very different Karate Kid and very different career paths for Macchio and the lucky winner of the Multiverse.
In the ’80s, Downey Jr. had a stable career playing bullies and movie sidekicks, and was even a member of the SNL cast during the 85-86 season, but he would find elusive success as a co-head of 1987 poster Less Than Zero and The Pick-up Artist.
Macchio would play the role of Daniel LaRusso in three Karate Kid films and then reprise the role, 30 years after The Karate Kid Part III, on Cobra Kai, which started as a YouTube Red series and is now a Netflix Original.
