Kilmer most recently appeared in “Top Gun: Maverick” in 2022 to reprise his infamous role as Lt. Tom “Iceman” Kazansky.

Although he could portray his character, he still had difficulty due to damage from a tracheostomy. Kilmer required the use of a breathing tube.

After his death, Kilmer was honored by “Top Gun” co-star Tom Cruise during a promotional event for “Mission: Impossible – The Final Reckoning.”

“I’d like to honor a dear friend of mine, Val Kilmer, for a moment,” Cruise said at CinemaCon, according to The Hollywood Reporter. “I can’t tell you how much I admired his work.

“If we just all take a moment to remember the wonderful time we had with him — let’s just take a moment. I wish you well on your next journey.”
