Stan's appearance in 2003's Daredevil (another character he co-created) is short but sweet. A young Matt Murdock helps save Stan's cameo career early on by stopping him from walking out in front of a bus whilst reading a newspaper, leaving the main man stunned by the blind hero's actions. Stan Lee isn't the only familiar name to appear in this movie either Frank Miller and Kevin Smith (both known for their work on Daredevil as writers) also make cameo appearances. Both are relatively minor in comparison though.
I have an addiction to achievements, a craving for new bands and a dream to become Captain America. I once finished second in a Mario Kart 7 tournament so I'm kind of a big deal.
