Like (TV) father, like (TV) son, I recall seeing Mark Lenard playing a Japanese character in an episode of Hawaii Five-0, the one starting Jack Lord.It's worse in season 5's "Butterfly," where Paris is supposedly able to convince real Japanese people in Japan that he's one of them. At least most of the actors playing Japanese characters in that episode were really Asian, even actually Japanese in a few cases -- except for Hawaii Five-O's Khigh Dhiegh, who made a career of playing Asians but was actually New Jersey-born Kenneth Dickerson, of English, Egyptian, and Sudanese descent.
I don't know how the audience reacted to seeing Lenard as a Japanese man, when the Hawaii Five-0 episode originally aired. I saw the episode many years later as a rerun. To my eyes, Lenard's appearance and performance was cringy and not very convincing.
Speaking of Jack Lord, I read that, before Shatner was in the picture, Roddenberry offered the role of Captain Kirk to Jack Lord. But Lord wanted a 50% cut of the profits, a piece of the action, so to speak. With that, Roddenberry rescinded the offer. What could have been but wasn't.
Getting back to Mission Impossible, Rollin and then Paris were the master of disguises within the IMF team. But that was somewhat misleading in reality.
I usually get a kick out of seeing Rollin or Paris rip off their mask at the end of an episode, because you know that, in reality, it wasn't actually the actor Landau or Nimoy who was in make-up while impersonating the character they were supposed to be impersonating during the episode.
For example, at the end of the episode "The Town", Rollin rips off the mask of the doctor (actor Will Geer). You knew that it wasn't actually Landau in disguise as the doctor during the episode.
It was, in reality, Will Geer acting as Rollin impersonating the doctor. But of course, in universe, it was Rollin who was in disguise the whole time that he was impersonating the doctor.
Another funny thing is that, oftentimes, after he rips off the mask, he would just dump it on the ground, leaving behind evidence of the con.
