Whilst “make a movie about a different superspy” may seem obvious, but it’s been done many times. There was a whole rash of them in the 60s when Doctor No was a big hit, mostly of the American Bond subtype, and there has been a steady flow ever since. Occasionally, they even feature female spies. Aside from a couple of TV shows (UNCLE, The Avengers) they are largely forgotten (Our Man Flint anyone?)
The sad fact is it’s hard to have a big hit with superheroes without the Marvel branding, a hit space adventure without the Star Wars branding, or spy adventure without the Bond branding.
