Trailer Details and Multiverse Conflict

The trailer also showcased the X-Men’s return, with Nightcrawler (Alan Cumming) and other mutants crossing over into the MCU. Production designer Gavin Bocquethas revealed that 80% of the film’s sets were practical, though Cumming criticized the heavy use of green screen, noting he often acted alone with “fake names” for characters.
Critical Reception and Fan Reactions
