This question already has an answer here:
While watching the Flash season 3 episode 5, I just saw Felicity Smoak reference “The Incredible Hulk”.
Then, after doing some research, I found out that’s also happened often on other shows of the Arrowverse.
I find it extremely odd with Marvel and DC being kind of rivals in the business. It’s like doing marketing for you competition.
What’s the reason behind those references instead of referencing DC superheroes?
