The initial box office predictions for 'The Marvels' were between $75-80 million domestically but have shrunk to between $60-65 million recently. Marvel Studios has struggled to reconnect with audiences in the post-'Avengers: Endgame' era, with mixed critical and fan reactions to projects like 'Eternals' and recent Disney+ shows. Issues like MCU oversaturation on Disney+ during the pandemic and some less well-received projects may have led to audience fatigue with the universe. A lower opening for 'The Marvels' could push Disney to consider a harder MCU reset in the future.
