Batman
Did you know that May marks Batman's 75th birthday? The billionaire in the cowl was introduced in Detective Comics #27 May 1939 edition (a comic that sold a few years ago for over a million dollars). He's aged well but trust funds will help that way. And Bruce Wayne had more money than God even before Batman was a cultural icon and DC and Warner Bros figured out how to make billions from trotting him out consistently. Warner Bros is planning a year-long celebration as well they should since their ownership of DC's superheroes on screen probably accounts for a nice sliver percentage of their profits.
I'd suggest a theme week here but after the past 25 years of movie blockbusters featuring the caped crusader, maybe I need a break. What say ye? Celebrate or Ignore? Or somewhere inbetween?
Quicksilver
One of the sexiest of superheroes (saith I), Magneto's son, the sometimes evil sometimes good super speed silver haired young fox turns 50 this very month. He's never been visualized onscreen but due to complicated rights issues we'll get him twice over in the fourteen months with Fox's X-Men Days of Future Past (played by Evan Peters in a terrible wig in 2014) and Marvel Studio's Avengers: Age of Ultron (Aaron Johnson with silver hair despite earlier awful suggestions he'd stay brunette in 2015). [Long story short: Scarlet Witch and Quicksilver as spawn of Magneto are connected to The X-Men mythology but more often connected to The Avengers in terms of regular appearances so both studios can use them provided they never mention their other heroic connections.]
Next month Daredevil and The Black Widow both turn 50. They were once lovers in the comics but due to rights issues they aren't really in each other's orbits onscreen.
The Black Widow is back very very quickly in Captain America: Winter Soldier and the latest incarnation of Daredevil will arrive whenever Netflix gets around to their planned series. That one is certain to be the most satisfying simply because it can't be worse than the movie version. I only pray they make him a redhead this time like he's supposed to be. Male gingers deserve their proxy heroes, too.
Namor turns 75 in April, the Green Goblin turns 50 in Julym, Scott Pilgrim (not really a superhero I know) turns 10 in 2004, and Hawkeye turns 50 in September
