Fun fact: there was a "reboot" series from, I believe, 1988-89. It came about because of a writer's strike. They simply re-used scripts from the original show and possibly had non-union script supervisors rewrite them to make them seem newer. It was not perhaps quite as good as the original, but close. Peter Graves starred in that one, too...and Greg Morris' son Phil took over his dad's role as the team technical whiz.
I remember the guest baddie in the initial episode was John DeLancie, "Q" from
Star Trek, as a hit man.
