Spoilers for the Thunderbolts ending and Thunderbolts post-credits scene follow.
Robert Downey Jr. might be going method for Avengers: Doomsday after breaking the cardinal rule of spoiling Thunderbolts before its opening weekend was even over. Taking to Instagram to praise the latest chapter in the MCU, the man who will return to the franchise as Doctor Doom said, "Just wow!!! Dinner and a show with the Old Avengers. So cool, fresh, and deep. Big congrats." Unfortunately, some fans picked up on the "Old Avengers" comment and quickly put the pieces together, finally realizing what the asterisk meant after all this time, before seeing it for themselves in theaters.
