Re: Downey's last?
Oh there should definitely be a decent gap in between RDJ's Stark and whoever the unlucky guy is who has to follow him. 7-10 years sounds about right.
2015 will not only see the MCU beat the HP franchise for the #1 WW spot but it will also see Marvel Studios pass Pixar in terms of WW grosses($8.585 billion). Marvel Studios/MCU avg. annual profit: $621m(there ain't none higher. HP was the closest runner up with $541m when it was active).
