John Mahoney (Marty Crane) would only have been 81 and possibly capable of reappearing, had he not died in 2018.
Interesting side note, Mahoney grew up where he was born, in England. Came to the U.S. at age 18.
True except his character had been in the Korean War and for the show to make sense you would have to suspend reality for Marty to be 97 or 98.
Of course they do that on Blue Bloods anyway, Tom Sellecks father’s character is in his 90’s.
