« How to make an Opera Star. Does that sound like the kind of film you'd be fascinated by? Me neither. [..] Yet for a non-opera fan, I found myself keenly interested yesterday at the Towne Cinema, when I went to see The Brave Bulls and stayed over to enjoy the National Film Board picture with it, Opera School. [...] It is a documentary, but with the added interest of a dramatic progression—that is, the advance of one pupil through three years at Opera School. It is a documentary, with no narrator. Lister Sinclair's scenario tells its own story as it goes along, never has to nudge us so we know what we're seeing, or to point out a moral. Produced by Guy Glover and directed by Gudrun Parker, Opera School was made here [in Toronto], mostly at the corner of University and College St., where the Royal Conservatory Opera School has its being and, to judge from this film, flourishes mightily. »
