Professor Hackenbacker, better known by his preferred alias of "Brains", is a character from the live-action Thunderbirds released in 2004. He has a son called Fermat and he is the designer and creator of all of the Thunderbird craft.
Trivia[]
- He was the first International Rescue victim to be mind controlled by the Hood.
- He has the same stutter as the original Brains. At a crucial moment in the film he dropped the stutter and yelled "damn it Jeff, wake up!". He resumed his stutter afterwards.
- His wife and Fermat's mother is never seen or mentioned in the film.
- The 2005 tie-in annual lists his first name as Fermat, possibly in confusion with his son.
