This is what makes the OT such an interesting trilogy:

Star Wars

-Written and Directed by GL, Produced by Gary Kurtz, Shot by Gil Taylor

Empire Strikes Back

-Directed by Irvin Kershner, Produced by Gary Kurtz, Screenplay by Leigh Brackett and Lawrence Kasdan, Shot by Peter Suschitzky

Return of the Jedi

-Directed by Richard Marquand, Produced by Howard Kazanjian, Screenplay by Kasdan and Lucas, Shot by Alan Hume and Alec Mills

Compare that to the PT, which was entirely shot by David Tattersall and entirely written and directed by Lucas with help on AOTC's screenplay from Jonathan Hales.
