"The imaginative experiments with animated clay figures begun last year in No Credit have, in this year's Proem, proved out as a suave and wholly integrated art form. The unique and wholly delightful work of Leonard Tregillus and Ralph Luce, jr., has here come handsomely of age — both technically and creatively. Proem, conceived as a preface to the theme of Carroll's Through the Looking Glass, is of far greater filmic stature than its already rented status permits it to be rated." Movie Makers, Dec. 1949, p. 470.
