After making episodic appearances in shows like "Unbreakable Kimmy Schmidt" and "Mistresses," Niles Fitch landed his breakout role as 17-year-old Randall on "This Is Us." This year may just be his biggest yet — Fitch is starring alongside Jennifer Coolidge, David Harbour, and Anthony Mackie in Netflix's forthcoming sci-fi film "We Have a Ghost," which, according to IMDb, is expected to hit the streaming platform later this year.
