Colour cinematography tends to brighten and cheapen natural colour. The problem was to counteract that. I realised that colour in films is nearer to … - Rouben Mamoulian

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.

In this unhappy, fragmented world of ours, overflowing with mutual suspicions, hostilities, violence, and destruction, we need a constructive force. Politics, economics, religions seem to fail. I think our best hope is in the arts. Today, the most powerful and universal and powerful medium of art and communication is in the film. In the last few years I've done a great deal of traveling to many countries, and I've been amazed at the impact of films on both the individuals and the societies of different nations. The influence is enormous. So we must all strive to elevate the quality of motion pictures. We must affirm and insist that the ultimate goal of a film, no matter what subject matter it deals with, is to add to the beauty and goodness of life, to the dignity of human beings and to our faith in a better future.

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.
