Josh Brolin recently said he'd be willing to return to the MCU as Thanos in future <em>Avengers </em>movies: "<em>Thanos has to fit if you’re going to bring him back. I would do anything that the Russos wanted me to do." </em>On the one hand, Brolin potentially coming back as Thanos could be very intriguing considering the villain's small role in the comics' <em>Secret Wars</em> event of 2015. That said, I'd be worried that Thanos could end up overshadowing newer villains, whether it's Doctor Doom or some other new threat to the MCU.
