While Kilmer reprised his role as Iceman in the action-packed film, he suffered from health issues amid his big on-screen return. 

Kilmer was diagnosed with throat cancer in 2015. Although he was able to play his role as Iceman alongside Cruise, the actor experienced difficulty due to damage from a tracheostomy.

"I can't speak without plugging this hole [in his throat]. You have to make the choice to breathe or to eat," he explained to People Magazine in 2021. "It's an obstacle that is very present with whoever sees me."

The reboot was released in November 2022 on Disney+.
