The Rabbit’s Foot can briefly be seen around the 1:36 mark of the Final Reckoning trailer in a shot that shows Ethan wrapping his gloved hand around the obviously dangerous bioweapon. This shot, notably, looks like it could have been pulled straight out of Mission: Impossible III. However, viewers are never shown Ethan physically retrieving the Rabbit’s Foot in that film

That means the shot featured in the Final Reckoning trailer is either a deleted visual from Mission: Impossible III or a new one created with a potentially de-aged Cruise. In all likelihood, viewers will have to wait for The Final Reckoning to hit theaters in summer 2025 to find out which of those two possibilities is correct.
