Joel Kim Booster has had quite the year. From a small voice acting role in Netflix's biggest film of all time, KPop Demon Hunters ("if they do a sequel, Romance is still available to be the new villain," he says of his character); to filming ABC's highly-anticipated Scrubs reboot (the OG cast members have been "so gracious and welcoming and so amped to have this new blood"); to Season 3 of his Emmy-nominated Apple TV+ series, , Booster's been booked and busy.
