He's probably been in more movies than any actor in Hollywood history

Hear more of James Hong's Hollywood tales in the latest episode of Great Big Story, a new podcast by CNN about the delightful, surprising stories all around us.

(CNN)James Hong is everywhere.

He spoke Mandarin with Keanu Reeves in "The Day the Earth Stood Still." He backflipped his way out of a fight in "Wayne's World 2." He was the supportive, noodle-loving Mr. Ping in "Kung Fu Panda." On television, he was the maître d' in the episode of "Seinfeld" titled "The Chinese Restaurant."
Without exaggeration, Hong might be the most prolific actor in Hollywood history. With more than 600 credits to his name, he may lay claim to the most credits of any actor, living or dead.

    Inspired by Chinese operas in Minneapolis

      Hong's path to stardom started, as many do, as a child practicing in front of a mirror. But he kept his acting aspirations from his parents.
        "Well, you know, Chinese parents want you to do some professional jobs rather than be an actor," Hong says. "Being an actor is like the last rung in the ladder of professions. They don't even call it a profession because it's shameful to demonstrate your feelings in front of an audience. You were taught to be kind of quiet and to keep to yourself."
        Still, he received some of his favorite acting inspiration from his father's herb shop in Minnesota.
          "All the laundrymen from Minneapolis had nothing to do on weekends, so they would gather at my father's store, herb store," Hong recalls. "I remember that, because we'd have those little wooden stools and they all gathered there, and they hired these Chinese opera people from San Francisco to come and do their thing ... I was only a little boy. You watch them with wide eyes, 'Wow! What a profession.'"
          With more than 600 acting credits, James Hong might be one of the most prolific actors in Hollywood history.

          He started his career as a civil engineer

          To please his parents, Hong graduated from the University of Southern California with a degree in civil engineering. While working for Los Angeles County building roads, he continued to try to find work as an actor and comedian.
          His big break came on a TV show called "You Bet Your Life," hosted by Groucho Marx.
          "I did impersonations of Groucho, James Cagney, and so forth," Hong said.
          His appearance was a hit. "I got the second-biggest fan mail ever on the Groucho Marx show," he said.
          That TV appearance landed him an agent, and with it, the start of a career in Hollywood.
          Besides his on-camera work, Hong has a long career as a voice-over actor, including a role as Mr. Ping in "Kung Fu Panda."
          "All of a sudden, they wanted me to be in a movie," Hong said. That movie was "Soldier of Fortune," a 1955 film starring Clark Gable.
          "It was just some kind of experience I never forgot, to act with Clark Gable. Then, right after, I got my union card and I started one after another. I had to quit civil engineering," Hong said.
          Soon enough, he was acting alongside the likes of John Wayne, William Holden and Jennifer Jones.

          Hong battled stereotypes along the way

          "From then on, it was 10 movies or TV [shows] a year," Hong recalls. Those early roles, however, were limiting, to say the least.
          "Asians were put into a movie or TV mainly as a gimmick," Hong said. "We were never thought of playing the main roles, the leading people. That's the way it was."
          Hong began his career during an era of flagrant yellowface in Hollywood, where white actors would routinely play Asian characters. Marlon Brando played an Okinawan local in "The Teahouse of the August Moon," Mickey Rooney played the bucktoothed Mr. Yunioshi in "Breakfast at Tiffany's," and John Wayne played Mongol emperor Genghis Khan in "The Conqueror."
          Even in "The New Adventures of Charlie Chan" — a crime TV series in which Hong played a supporting role — Irish American actor J. Carrol Naish played the lead as a Chinese American detective.
          "Any other movie that demanded an Asian lead most of the time was played by Caucasian actors with their eyes taped up and their little teeth," Hong said. "I ended up in the early career mostly playing laundrymen, or persecuted Chinamen ... it was tough, very tough, to get out of the mold."
          But Hong didn't let Hollywood's narrow lens limit his abilities.
          "I did the best as an actor to overcome the cliché-ness because I had to in order to keep working," Hong said. "I took those roles and then I used what my teachers had taught me and put the real feelings, even if it's a villain ... I try to find what makes the person really that person."
          Hong was the voice of Chi-Fu, the antagonist in Disney's "Mulan."
          That doesn't mean Hong didn't also stand up against misrepresentation. In 1962, he was given a script for a film called "The Confessions of an Opium Eater," directed by Albert Zugsmith.
          "I read the script, I said, 'This is terrible,'" Hong said. "All the roles were the opium dope people and the prostitutes and so forth."
          He organized a group of people to approach Zugsmith's office to make a case for a rewrite.
          "I said, 'This is not a good image of the Chinese ... You've got to improve the image of the Asians here," Hong said. Zugsmith, however, would not be convinced, and the movie continued on with production.

          It led him to start his very own theater company

          Realizing that Hollywood wouldn't be able to provide the roles Asian Americans deserved, Hong set out to carve his own space. Along with actor Mako Iwamatsu, Hong helped organize an Asian American acting group in Los Angeles. Their first production was "Rashomon," a stage play based on two short stories written by Japanese author Ryūnosuke Akutagawa and adapted into film by Akira Kurosawa.
          "That started the industry noticing who we were," Hong said. "We weren't just extras, or gimmick people. We were in a play that we organized. We were the main, lead people. We were the actors. And we commanded attention."
          That acting group turned into the legendary theater group, East West Players.
          "East West Players were formulated to showcase works by Asians, who wrote the play, who designed the stage, who act in the play," Hong said. "It was all done by Asian people, professional people."
          And Hong knows better than anyone the importance of having a space for Asian American creatives in Hollywood, where roles are still lacking.
          At 91 years old, Hong has no plans of retiring any time soon.
          "Even though the actors and singers have talent, they can't move forward because there are not enough roles," Hong said. "That's a shame, because it's a waste of good talent. We can't express ourselves in the way we want to in the mainstream movies and TV because it's controlled by somebody else." But he is still confident that change is coming soon.
          "Asians are beginning to do their own plays and own TV series and movies and getting big box office. So it's only a matter of time."

          Helped usher in new generations of Asian American actors

          East West Players has nurtured great talent over its 55 years. Actors such as Randall Park, George Takei, John Cho and Daniel Dae Kim have all been associated with the theater. And according to East West Players' current artistic director, it is thought that at one point, 70% of Asian American actors in Hollywood had a connection to East West Players.
          "You know, seeing this thing grow as it is to what it is ... I still can't believe it," Hong said of the theater company. "I have to be proud of what I've done. But you can't be too proud, because there's too much work to do."
          Even at 91 years old, Hong isn't ready to slow down any time soon.
            "I could just retire on my pension, my (Screen Actors Guild) pension, and go to Europe and tour, and India," Hong says. "But something inside me, inside of James Hong, wants to keep on going and do more movies and progress ... I'm going to do other movies until I can't walk anymore and can't talk anymore. Then, I'll take that tour."
            As of July 2020, Hong has 469 TV credits, 149 feature films, 32 short films and 22 video games to his IMDB page. That makes for a total of 672 credits, and a breathtaking legacy that will live on in Hollywood history.
