We picked up on this over at All Shook Down today. It seems that a San Francisco convenience store cashier (or practical-knee slapper actor) received neither credit nor pay for his appearance in Will Smith's Oscar-baiting tear jerker The Pursuit of Happyness (2006). In this Daily Show segment ripoff, he goes into detail about being chewed up by the big, bad Hollywood machine.
Also, anyone forced to appear in a scene with Mr. Smith's hyper-precocious offspring -- who wants to star in a remake of The Karate Kid, God help us all -- deserves some sort of compensation for his time, right?
