April O’Neil (Judith Hoag)
Playing reporter April O’Neil was Judith Hoag’s big break and she followed it up with a role in Robin Williams’ Cadillac Man the same year. Since then she’s made appearances in shows like Quantum Leap, Walker Texas Ranger, Murder She Wrote, and JAG. Hoag was a recurring cast member for five years on HBO’s Big Love and is now a regular on ABC’s country-tinged drama, Nashville.
Ralphael (Josh Pais)
As mentioned in our Ninja Turtles facts piece, Josh Pais was the only actor to both wear the turtle suit and provide his character’s voice. Teenage Mutant Ninja Turtles was one of Pais’ earliest roles and he went on to land smaller parts in some pretty high-profile movies over the years including Rounders and A Beautiful Mind. He’s been a recurring cast member on Law & Order for nine seasons as well as currently making regular appearances on Showtime’s Ray Donovan.
Splinter (Kevin Clash)
Kevin Clash is best known for providing the voice of Elmo, and was a regular on Sesame Street from 1982-2013. During that time he also provided the voice for the baby dino on the short-lived 90s sitcom Dinosaurs as well as something called Dog City. Following his departure from Sesame Street after an alleged sex abuse scandal, Clash has kept a rather low profile.
Head Thug (Sam Rockwell)
Rockwell had one of the smallest parts in the Ninja Turtles movie, not even getting a proper name for his character, but simply “head thug.” The head thug went on to do big things of course, becoming a bigger name than anyone else in the cast with large roles in blockbusters (Iron Man 2) and indies (Choke) alike. Currently, Rockwell is filming a remake of the 80s supernatural horror, Poltergeist.
Casey Jones (Elias Koteas)
Next to Rockwell, Elias Koteas has probably had the strongest career following his hockey stick-wielding days with the turtles. Koteas is an in-demand character actor, often playing a cop or criminal with long list of movie credits to his name like, The Thin Red Line, Zodiac, Gattaca, and Now You See Me. Koteas was a regular on the gone-to-soon AMC series, The Killing, and is currently a cast member on Chicago P.D.
