Understanding Gershwin

Israeli pianist Astrith Baltsan explains the music of George Gershwin before a performance of Rhapsody in Blue with the
Israel Philharmonic in a 2001 live broadcast on Israel TV.

Which brought to mind one of the all-time-great opening sequences of a major motion picture.

The only one I can think of that comes close to this is George C. Scott’s opening speech in Patton.  The opening sequence in Silverado is also terrific.  Any other great opening sequences?
