The movie is David and Lisa from 1962, starring Keir Dullea and the lovely, late Janet Margolin. (I really want to see this again in its entirety.)
The question (for anyone who's actually ever seen it)... was the character of "Sheldon Cooper" on The Big Bang television series, played by Jim Parsons, based on the character of "David Clemens" in David and Lisa?
Some of the similarities are uncannily coincidental (if it is coincidence at all)... they both have genius level intellects, are both anal retentive, both come off as arrogantly intellectually-superior & anti-social, have issues with personal physical contact, are socially inept in the same ways, have similar phobias, and even many of their mannerisms are the same.
The big difference is that Sheldon's eccentricities are played for laughs while David was featured in a somewhat serious film about mental illness.
