A hint that was dropped from Underworld star Kate Beckinsale last year indicated that she knew of plans to bring Blade back into the fold.
There could be some benefit to Mackie taking on the mantle of Blade.
The fans may have loved Wesley Snipes in the role, and though he is open to a return there isn’t a lot of future in Snipes as Blade.
The MCU has no public plans to bring Blade back at this time, according to Marvel Studios President Kevin Feige, but one can never be too certain about what Marvel is working on, behind closed doors.
