Val Kilmer struggled to speak during his first public appearance since denying reports that he had cancer.

In video footage recorded at the event, the actor, 56, presented the film version of his one-man play Citizen Twain in Los Angeles on Thursday, where he took the stage to introduce the project and answer audience members’ questions. Kilmer slurred as he spoke and continuously dabbed his mouth with a tissue.

He told the audience that he had to cancel his upcoming tour for the play because his “tongue swelled.”

“I went into rehearsals down in Florida and started having trouble with my speech,” he said. “Obviously I’m still recovering. My tongue swelled up and I canceled the tour. As I’m recovering I’m showing this.”

While he declined to discuss his health any further, the actor appeared to be in good spirits throughout the night. Kilmer cracked numerous jokes, causing the audience to break out in laughter.

The event comes after Kilmer denied Michael Douglas’ claims that he was battling oral cancer. Kilmer addressed the comments in a Facebook post, writing that after seeing a specialist to get a diagnosis for a lump in his throat, he was told he did not have cancer.

“I have no cancer whatsoever,” he wrote. “I still have a swollen tongue and am rehabbing steadily.”
