Infinity War
Marvel took 10 years - 17 films, with 9 more in production - generating USD 13.4 billion = equivalent to any third GDP world country. This is what i call creative economy. what i love it - their inter-connected universe, like you reading their comic books - their editor will put a footnote if you dont know what you going on in a certain panel. To invade the world, you simply need a gamble, an inch of luck ( Iron Man 2008 was shot without a finished script and yes down and out RDJ ), persistence and a grand plan. Put it simply Marvel is like Thanos.
