The Case of the Red-Faced Thespian - S4-E12
Plot hole: Magnum mentions that he spoke "one hour ago" to Robin, getting the description of Lowell Xavier Jameson. All the suspects are at the estate, and Tanaka arrived, apparently with an arrest warrant for Higgins, when Magnum still hadn't spoken with Robin. Magnum did have to bargain for Tanaka to put off the operations by two hours; it does not make sense that he'd be around at the estate one 1 full hour more for unexplained reasons.

Revealing mistake: In the climax of the episode, Magnum tackles Higgins to the ground - but it's an obvious stunt double. (00:45:10)
The Case of the Red-Faced Thespian - S4-E12
Other mistake: As said in the ending, Lady Cynthia Warrington-Stout was on Higgins' bed when she was found; the room looks nothing like Higgins' room as shown in Foiled Again (3-8).
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Magnum puts the register on the armchair while Higgins is looking at the invitations. He pulls away, but in the next shot he's still hunched over the armchair. (00:36:40)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Higgins, back in his wits, walks into the studio while Magnum is brainstorming with TC and Rick. He spots the invitations and examines them; as he approaches them you can see they are spread out in a fan, while at the beginning of the scene they were stacked in a neat pile. (00:36:15)
The Case of the Red-Faced Thespian - S4-E12
Character mistake: Magnum quotes in his mind (right after the $20,000 turns up in Higgins' room) and then out loud (during the denouement) that "Old wounds heal slowly." The quote is from a movie he watched earlier...but it said "DEEP wounds heal better slowly." (00:30:55 - 00:35:40)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: When Valerie says "You can't keep me here!" sitting on the armchair, her shadow is in a completely different spot of the seat compared to the wider angle. (00:34:50)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Magnum asks Valerie Kane to show him her legs. Much to the viewer's enjoyment, she does; she also does it putting her right arm parallel to the edge of the desk, but in the following shot it's just like in the one before, across the desk, on the papers. (00:32:50)
The Case of the Red-Faced Thespian - S4-E12
Revealing mistake: During the attempt to Higgins' life, a knife gets stuck into a tree. It hits exactly the spot where a notch was visible already. After a cut to people running scared in every direction, the tree is again shown, and the knife is now stuck in another spot. (00:31:50)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Sir Fearing Pangborn announces the "encore selection" with a hand on the sheet/tunic, but he had that hand low in the previous shot. (00:31:50)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: In the midst of the 'murder investigation', Magnum decides to just chill and watch a movie. He sits on the couch reciting the lines off the top of his head and with a falsetto. Notice that at the left edge of the frame there's a book popping in, roughly positioned between two pillows. You see the book again in the reaction overhead shot when TC calls Magnum to help out of the predicament Higgins is in, but it's more to the left. (00:30:25)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Lady Cynthia Warrington-Stout gets up with Rick after the swim. She has her towel and shoes in her left hand, which becomes the right when Archer Hayes is spying on them. (00:21:00)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Inez Stuart signs up the program for TC; a program that is rolled up, opened, closed, rolled up again. (00:17:40)
The Case of the Red-Faced Thespian - S4-E12
Revealing mistake: After the first performance of "Sir Fearing Pangborn", the Douglas Fairbanks and John Barrymore impersonators do another spot of dueling. The railing to the right of the stairs wobbles significantly when touched, certainly not the kind of build for a luxury home like Robin Masters', but rather a stage's. (00:12:30)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: The close-up of Robin's door with the "WRITING" sign on the handle features a shadow completely different from the one Magnum's body casts in the previous and following shot. (00:09:45)
The Case of the Red-Faced Thespian - S4-E12
Plot hole: Magnum is incredibly slow to unveil the charade at the base of the episode; he does it based on something marginal (Robin Masters does not do "research" for his novels), but he completely overlooks the key plot point of 1-17 "J. Digger Doyle" was that he does not use a typewriter, but he dictates the novels.
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Magnum just met the Athertons. The secretary asks him to speak in private, and Mrs. Atherton gives him a knowing look. She holds her foulard in hand differently between the two shots. (00:09:10)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: When Magnum asks Hayes what's the secretary doing at the estate and not in Greece, he has both hands on the card. Next shot and, like in previous ones by the same angle, his right hand is on the piano. (00:07:55)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Archer Hayes shows Magnum the invite with the wrong time. He hands it with his right, which turns into the left in the reverse shot. (00:07:40)
