The dawn of cinema had no audio; silent movies created an atmosphere with music and the use of cue cards. Take a 3-5 minute trailer of a modern movie and render it in the form os the silent era- convert to black and white, add effects to make it look antiquated, replace the audio with a musical sound track, and add title cards for the dialogue. As a prime example, see Silent Star Wars.
One of the best sources for music is Incompetech or the Internet Archive. For the title cards, try a google image search
