I'm suprised the budget was so high for this movie. I understood why they wanted to lower down the costs substantially on this film.
One of the reasons Spider-Man 4 was cancelled was because the cost kept going higher and higher on each film and people were always expecting more.
They couldn't really keep up with the costs so believed going for a much cheaper reboot from scratch would benifit them more.
But this film is now the same cost as Spider-Man 2, and while I'm not complaining, it makes me worried that by the 3rd film (if there is one) it would be too expensive to produce anymore. Which is why I was quite happy with the slightly cheaper approach.
