The web comic Vengador has been adapted for a live action trailer. This shows that a small man can make it and with hopes and enough support this could really be a great movie! The comic has a great story line and week by week it gets better.
Even though the costume is pretty cheap and the effects may not be A grade. This is pretty good if you ask me for a one man band.
