MTV talked to animation director Anthony LaMolinara who discussed the restrictions on Spidey for his upcoming third adventure.
“The character Spider-Man, each time, is something you have to develop. It’s a learning curve. Whereas, when you get a new character you’re going to put all of the bells and whistles you can on him. And it has to [be like that] — Spider-Man can’t take too big of a leap. No pun intended.”
