[In 1927] Porgy made me overnight. In it I tried all my ideas of a dramatic integration of many elements ... At this time I felt it should be possibl… - Rouben Mamoulian

[Mamoulian] "[T]he majority of the films in the future will be done in color. Perhaps not immediately. Perhaps it will take three years or five years. But there must be progress and development in the cinema. Color will enrich it. It is part of that progress.

Shakespeare used the soliloquy to give oral expression to thoughts. Since then the soliloquy had become obsolete. But it was a wonderful device: so I wanted to use a close-up of Sylvia Sidney, alone, in prison, and superimpose over it all her impressions and recollections. Again, everybody insisted it was impossible and that the audience would never understand what was going on. I argued that in the silent cinema they had used – and the audience had accepted – stylisation: simile, visual poetry. So why not in sound? That’s what I wanted to do with sound and, later, with colour. Now, of course, this use of audible thoughts over a silent close-up has become a convention.

I lifted the sound-proofed camera off its feet and set it in motion on pneumatic tires. Scenes moved out of one room and into others without halt. I tried to introduce what I call counterpoint of [a]ction and dialogue. The camera flew, jerked, floated and rolled, discarding its stubborn tripod-legs for a set odfwired wheels that raced over the studio floors.
"The camera here becomes descriuptive in a new sort of way. Where a break in the ordinary film to allow for a close-up has been the modus-operandi, I now guide my lens along a strraight and continuous line, without breaks in continuity, without needless exolanatory speeches and also sans the printed subtitle.
