As important as he was in the pantheon of Greek gods, Apollo is remarkably absent in popular culture. Here are the few examples:
Apollo is seen briefly in the Beethoven Pastoral symphony segment in FANTASIA
Michael Forest was Apollo in a STAR TREK episode called "Who Mourns for Adonais?"
This TV episode is probably the only reasonable interpretation of the Sun god.
Apollo in comic book form
Apollo (Corey Sevier, sitting) made an appearance in IMMORTALS no matter how fleeting it was.
