George Takei hit out at his fellow Star Trek alum William Shatner for taking a historic space journey at the age of 90 - reigniting a decades-long feud that began on the set of the 1960s sci-fi show.
Asked about his thoughts on William Shatner's trip 62 miles above the surface of the Earth on Wednesday, Takei said: 'He's boldly going where other people have gone before,' mocking Shatner's popular phrase as Captain Kirk.
'He's a guinea pig, 90 years old and it's important to find out what happens,' Takei added during the Broadway opening of Thoughts of a Colored Man on Wednesday night, according to Page Six.
'So 90 years old is going to show a great deal more on the wear and tear on the human body, so he'll be a good specimen to study. Although he's not the fittest specimen of 90 years old, so he'll be a specimen that's unfit!'
Shatner and newly minted astronauts Chris Boshuizen, Glen de Vries and Audrey Powers spent three minutes in weightlessness aboard Blue Origin's New Shepard rocket earlier that day.

Shatner became the oldest person in space, eclipsing the previous record set by Wally Funk, 82, on a similar jaunt on a Jeff Bezos-owned spaceship in July, by eight years.
Takei, 84, has hit out at Shatner before.
Their feud apparently began during filming of the 79-episode show, with Takei accusing Shatner of ignoring him on set.
He also accused him of changing the script of the 1989 film Star Trek V so that Takei's character, Hikaru Sulu, would not receive command of a spaceship, according to
