This movie came out in 1983. Starring the incomparable Christopher Walken, and directed by (surprise, surprise!) David Cronenberg, this movie tells the story of Johnny Smith (how much more everyman of a name can that be!), who develops precognition, as a result of a terrible car accident.
I wanted to share this, as it is yet another influence on my views of the development of the Psionicist class.
Again, this supports the idea that "anyone" can be cursed with the development of a psionic ability, thus allowing for psionics to be added to a D&D campaign, without having some insurmountable dice-roll for the character to obtain psionics.
