William Shatner celebrates his 93rd birthday on The Kelly Clarkson Show

It's hard to imagine, difficult to process, but William Shatner turned 93 today. The iconic actor has been promoting his documentary, You Can Call Me Bill, and stopped by The Kelly Clarkson Show where she was ready to celebrate with him.

Looking vastly younger than his age, Shatner told Clarkson that he wasn't 93; he was 54, and by all accounts, he could be as the man doesn't seem to age. Not only is there no outward evidence that he has spent over nine decades on this Earth, he is as sharp and witty as ever, still the same actor who brought Captain James T. Kirk to life on our screens on Star Trek: The Original Series back in 1966.

Kelly Clarkson was ready to celebrate with him and, at his request, skipped the cake and brought in a massive veggie pizza which shocked Shatner. Before they made it to the pizza, Kelly congratulated him for his birthday, telling him not everyone makes it to 93. Shatner jokingly responded that he knew because they kept dropping around him. He is one of three remaining stars from The Original Series, along with 87-year-old Walter Koenig who portrayed Ensign Chekov, and 86-year-old George Takei who portrayed Lt. Sulu.

Today marks the opening of the documentary that invites us in for a look at Shatner's life through the years. The film has a 90% score on Rotten Tomatoes with Clint Worthington of RogerEbert.com writing "it's hard to tell where James T. Kirk ends and William Shatner begins."

""I've turned down a lot of offers to do documentaries before. But I don't have long to live. Whether I keel over as I'm speaking to you or 10 years from now, my time is limited, so that's very much a factor.”

The sad thing is that the older a person gets, the wiser they become and then they die with all that knowledge. And it's gone,"

Earlier this month, Shatner told Variety [via People] that he'd turned down a lot of offers to do documentaries before, but he didn't have long to live. He said that this was his way of "reaching out" to his loved ones. And it's something they will always have to remember him by. And so will we. But right now, we'd rather focus all happy thoughts on Shatner's 93rd birthday.
