Various screenwriters read this blog, so if anybody is looking for supporting characters for a superhero movie, here's my advice: read up on the billionaire Candy Brothers, whose firm Candy & Candy serves as real estate developers and interior decorators for oligarchs, oil sheikhs, and hedge fund guys. The pages on Google read like headlines of newspapers twirling in an old-fashioned 1930s movie montage:

• The Real Estalker: The Candy Brothers Do It Again
• The Candy Brothers Sell Their Monaco Penthouse For A Whopping ...
• Candy Brothers in Monaco Make Millions in London Housing Slump ...
• Candy brothers lose millions of dollars on LA property deal that ...
• Billionaire Candy brothers were duped by con men - Telegraph

and so forth and so on. Your main problem would be how to make the Candy Brothers sound more believable so they'd fit into a comic book movie more plausibly.
