John Adams High may be a reference to Daniels' time spent portraying John Adams in 1776.
Daniels once said his least favorite role was that of 1967's "Captain Nice", which was an unsuccessful attempt by NBC to capitalize on the success of ABC's smash hit series Batman (1966-68).
Daniels reprised the role of KITT on multiple occasions, including the 1991 TV movie Knight Rider 2000 and in two episodes of The Simpsons (1998, 2004); he also reprised the role in 2008 when Mio Technologies released a limited edition Knight Rider GPS system that featured Daniels' voice giving directional information.
