Trivia: When Hiro buys the comic book, he pays with a 1000 yen note, which is a typical price for manga in Japan. This translates into approximately $8.48 American. As a typical 2006 newsstand price for comics is about $2.99, the vendor actually got more than his money's worth.
Trivia: There are a number of other Star Trek references in Heroes. In episode 15 (Run!), Hope refers to Hiro as "Sulu", and at one point (and several other times throughout the show) Hiro gives the Vulcan hand symbol that Spock always used when he would say "live long and prosper". Zachary Quinto, who plays Sylar, would also later play Spock in the 2009 reboot Star Trek.
Trivia: Masi Oka (Hiro), who has an IQ of 180, appeared on the August 31, 1987 cover of "Time Magazine" for an article called "Those Asian-American Whiz Kids". Masi, who was 12 years old at the time, is the boy on the left of the cover which can be seen here: http://img.timeinc.net/time/magazine/archive/covers/1987/1101870831_400.jpg
Trivia: The title "Seven Minutes to Midnight" refers to the Doomsday Clock that the Bulletin of Atomic Scientists prints to represent the global nuclear threat. The clock was originally started at seven minutes to midnight when it was introduced during the Cold War and it was also seven minutes to midnight when this episode of Heroes aired.
