Just a note: If you happen to be in New York City or Los Angeles, you can watch all of the "CBS Children's Hour" specials, including "Toby", at the Paley Center for Media (formerly the Museum of Television and Radio). Unfortunately, none of the CCFF films were available.
I remember this tv film, it must have been broadcast in late '69/early '70. In the TV guide the tag line read: "Toby was the smartest kid in town...and the loneliest."
For a 10-year-old, Toby was a math-whiz; I remember the scene where he multiplied 2-digit quantities in his head (like 43 x 78 = 3354) and he got them right - every time.
In playground scenes, he demonstrated how he couldn't swing at a softball without spinning around and landing on his can - every time.
From the day he arrived, Tobe found the quickest route to being the most unpopular kid in class: a genius with highest marks and lowest self-esteem, ohhhhhh boy.
But there's a happy ending, it shows him and the big bully together, throwing rocks at the haunted house and laughing themselves silly.
While this film is not available, you can watch J. T. at the University of Georgia Peabody Collection at http://www5.galib.uga.edu/media/collections/peabody/index.html. I was able to find the miniseries "Studs Lonigan" there also. Not really on topic but maybe helpful.
