You gotta love gifs. I started fooling around with a few frames of movie footage for fun when I made my Superherohype.com avatar for my profile. This was in like 2004 I believe. A year or 2 away from Spiderman3. One night I fooled around with footage from Underworld, Spawn and Spiderman1 and 2. What followed was this rather sloppy gif below. It garnered enough attention though to inspire to make a few fake Spiderman3 trailers. I'm not really proud of any of them.
Note: remember this was made a year or 2 before ANY spidey3 footage was seen.
