Creativity, because it’s 2017 The Mummy is being rebooted

Can anyone explain to me why The Mummy, a B-list franchise from the turn of the century, is getting a reboot? In particular, a reboot with Tom Cruise, who is definitely an A-list actor?

When I first heard that The Mummy was getting rebooted with Tom Cruise I assumed it was some fan-made trailer. Obviously I don’t know the entertainment industry logic here, but I think understanding that logic might give us a window into the economic and social history of this industrial sector in our age.
