I vaguely recall seeing Mask when I was a kid, but only recently learned A) it was directed by Peter Bogdanovich and B) there’s a well-regarded director’s cut available on DVD.
The film is very unconventional for the genre of disabled-person-beating-the-odds. Roy, doomed to die from Craniodiaphyseal dysplasia, loses his friend, his girl, and dies in his sleep never fulfilling his dream of traveling Europe. And yet, it is nevertheless moving and even uplifting. I think one reason is the sympathetic matter-of-fact presentation of a biker gang, a group often maligned or at least treated condescendingly by Hollywood.
