3. Trask's Size/Ethnicity
Recasting is an occasional necessity in film franchises, as sometimes actors need to be replaced for a host of reasons. The X-Men series is no different, though its latest change is pushing it a little bit, as the character played by an elderly black man has been reimagined as a middle-aged white dwarf. Details of Peter Dinklages casting in X-Men: Days of Futures Past were first revealed back in February, though it wasnt until Comic Con last week that he was officially confirmed to be playing Bolivar Trask, a scientist responsible for the creation of the mutant-hunting Sentinel robots. X-Men: The Last Stand, however, had Bill Duke play Trask, who functioned as part of the Department of Homeland Security with no apparent dislike of mutants or connection to robotics programs. The most convenient workaround is that Dukes character was only ever referred to as Secretary Trask and never by his first name, meaning that Dinklages character can theoretically be differentiated from his namesake with the explanation that the two are different individuals who merely share an uncommon surname.
