In "[[Metamorphosis (Star Trek: The Original Series)|Metamorphosis]]", Cochrane was played by [[Glenn Corbett]], who was 34 at the time of that episode's airing. In ''[[Star Trek: First Contact]]'', Cochrane was played by the 56-year-old [[James Cromwell]], at a point when the character, in 2063, would have been approximately 33 years old.<ref>The character was stated in "Metamorphosis" to have been 87 years old in 2117, and was therefore born in 2030, as pointed out by ''The Star Trek Encyclopedia''. Page 26 of ''The Star Trek Chronology'' (second edition) also gives 2030 as his year of birth.</ref> ''The Star Trek Encyclopedia'' explains this discrepancy by theorizing that Cochrane's aged appearance in 2063 was the result of [[radiation poisoning]], and that when he encountered the Companion, the Companion reversed these effects, and restored his youthful appearance.<ref name="Encyc"/>
