2. Dan Aykroyd - Casper
Original Role - Ray Stanz: expert on the paranormal and the occult. One of the key members of the Ghostbusters. Cameo Role - Ray Stanz: still an expert on the paranormal and the occult. Now a solo Ghostbuster for hire. Probable Explanation: Well either he went solo or the other Ghostbusters are very busy at the moment. I would hate to think of the Ghostbusters disbanding so I'll go with busy which would not be such a odd thing to consider. With Venkman being a family man now, Spengler devoted to his science, and people forgetting the other guy altogether (apologies to Ernie Hudson), it easy to see how Stanz would have a lot of free time on his hands to go bust some ghosts on his own. Although he'll probably need some help for as the clip from Casper illustrates he's not so successful as a one man team. http://www.youtube.com/watch?v=kSpvtwt-4HU
