According to The Hollywood Reporter, Gunn visibly "bristled" at a question about the DCU "sharing" Pattinson with Matt Reeves, director of "The Batman" and the upcoming "The Batman 2". Gunn confirmed that "no serious conversations" were had about Pattinson playing Batman in the DCU.

Robert Pattinson is most likely not going to have a role in the DCU, but never say never. DC Studios boss James Gunn said that it was "very unlikely" (via Variety) and "certainly not the plan" (via Collider) that Robert Pattinson would play Batman in upcoming The Brave and the Bold.

Robert Pattinson was established as our current Dark Knight in writer and director Matt Reeves ’ The Batman before the big shake up at DC when James Gunn and Peter Safran stepped in to be the co-CEOs of the DC Film Department at Warner Bros.
