Directorial duo Adil El Arbi and Bilall Fallah have reflected on their “painful” decision to step away from helming Beverly Hills Cop 4 in favor of the cancelled Batgirl movie. Featuring the return of Eddie Murphy to the iconic role of the wisecracking Detective Axel Foley, El Arbi and Fallah had originally been attached to the project as far back as 2016. Despite a series of developmental and COVID-19-related delays, the Belgian directors had initially confirmed they were still involved in the project as recently as 2020, though would later choose to depart to work on the now infamously cancelled Batgirl movie.
