Post heart attack, Antonio Banderas is relishing “Being Alive.”

Banderas, currently starring in a production of the Stephen Sondheim musical “Company” in Madrid, is making the press rounds in support of his new film “Puss in Boots: The Last Wish,” and he’s discussing his 2017 heart attack in-depth for the first time.

“I realized that it probably was one of the best things that ever happened in my life because the things that were not important and I was worried every day about them, meaningless,” he told Page Six.

“I was like, why am I worried about that if I’m going to die?” he said. “I knew always [that I was going to die], but now I know. I’ve seen it right here.”

“Puss in Boots” also deals with mortality, as Banderas’ titular character discovers he’s down to one of his nine lives and embarks upon a quest to discover the Last Wish and restore all nine.
