- "Nathan, who is sixteen now, the first word I think he learned was 'Kenner'."
- ―Mark Hamill, on the preponderance of Star Wars toys in their home, during an episode of the television show Personal FX
During the filming of Star Wars: Episode V The Empire Strikes Back, Mark Hamill was accompanied in Finse, Norway, by his wife Marilou, who was several months pregnant. In anticipation of a premature birth, the Hamills had brought medical supplies and a giant teddy bear with them. Nathan was born early on the Monday morning on which his father was meant to play a scene in which Luke manages to grab onto an electronic weather vane after emerging from the underside Cloud City. Despite having stayed up all night, Mark Hamill arrived on time at the set to film his fall from Cloud City onto the exterior of the Millennium Falcon.
He made one cameo appearances in Star Wars: Episode I The Phantom Menace. In an interview with the Star Wars Insider magazine, Hamill referred this character as "Rehtul Minnau", a name which was later canonized in Teckla Minnau's entry in the StarWars.com Databank.
Not too long after his appearances in The Phantom Menace, Nathan starred in an animated feature called Earth Day alongside his father.
