Kay Steiger wonders why there are so few films on women with disabilities:
Though not super common, stories about a protagonist overcoming the complications of a disability are getting some attention, what with the Oscar-winning The King's Speech. … But what you don't see in these types of stories are female protagonists. An obvious candidate for a story like this would be a biopic of deaf-and-dumb heroine Hellen Keller, but no such major film adaptation has been done, save a documentary about her released in 1954.
The recent Temple Grandin flick is an exception to this rule.
