The 93-year-old actor played the starship commander in three seasons of the original TV show between 1966 and 1969 and five movies before the character was killed off in his sixth movie appearance in 1994's 'Star Trek Generations' – but Shatner is adamant he'd be happy to bring Kirk back if the story made sense.
Speaking to The Canadian Press, he explained: "It’s an intriguing idea [bringing Kirk back]. It’s almost impossible, but it was a great role and so well-written, and if there were a reason to be there not just to make a cameo appearance, but if there were a genuine reason for the character appearing, I might consider it."
Shatner went on to mull over the use of technology which de-ages actors and would allow him to play a young version of Kirk as well as a scenario in which the captain could be physically resurrected.
He added: "A company that wants to freeze my body and my brain for the future might be a way of going about it. We’ve got Captain Kirk’s brain frozen here.’ There’s a scenario. ‘Let’s see if we can bring back a little bit of this, a little salt, a little pepper. Oh, look at that. Here comes Captain Kirk!"
Shatner latest screen project is the documentary 'You Can Call Me Bill' which looks back over his life and career and he recently opened up about how he stays healthy well into his 90s.
He told PEOPLE: "Just staying engaged in life, to stay curious. But the luck has a lot to do with it in your health.
"Your life's energy, the soul energy of your body is a product of health. If you're sick, you can't be energetic. You're dying. So my luck has been, I've been healthy all my life."
