Mask is a wonderful movie, a story of high spirits and hope and courage.

Roger Ebert

Chicago Sun-Times

All of the performances are limited by the material and, in the case of Mr. Stoltz, by Michael Westmore's quite spectacular makeup. The exception - and the film's best sequence - occurs when Rusty's very middle-class, well-meaning parents, played by Estelle Getty and Richard Dysart, come to visit. In these few, brief minutes, Mask becomes specific and interesting. Otherwise it's the kind of story that would work better as a television feature.

Stoltz is simply amazing in the variety, the humor and the absolute lack of self-pity with which he draws Rocky, whose spirit soars so far beyond his body.
