Alfred Hitchcock produced his film Dial M for Murder in 3D, but for the purpose of maximizing profits the movie was released in 2D because not all cinemas were able to display 3D films.
Alfred Hitchcocki film "Dial M for Murder" oli algselt tehtud 3D-s, kuid maksimaalse kasumi teenimiseks lasti välja 2D-filmina, sest kõik kinod ei olnud võimelised 3D-filme näitama.
