AMERICAN SPLENDOR / **** (R): "The Letterman sequences have the fascination of an approaching train wreck. Pekar really was a regular on the program in the 1980s, where he did not change in the slightest degree from the real Harvey. He gave as good as he got, until his resentments, angers and grudges led him to question the fundamental realities of the show itself, and then he was bounced. We see real Letterman footage, and then a fictional re-creation of Pekar's final show. Letterman is not a bad guy, but he has a show to do, and Pekar is a good guest following his own agenda up to a point, but then he goes far, far beyond that point. When I talked with Pekar at Cannes, he confided that after Letterman essentially fired him and went to a commercial break, Dave leaned over and whispered into Harvey's ear: 'You blew a good thing.'"
