- A low-level operative breaks cover in a record shop when speaking to Hunt apparently just to Squee! about all the ludicrous missions he's pulled off. But the record she hands him is later shown to be a message directly from the Syndicate, and Solomon Lane, its leader, is present in the shop throughout the whole scene, and kills her at the end. Maybe she was actually trying to tip Ethan off with an Out-of-Character Alert...
- When the CIA are trying to apprehend Ethan in Havana, Hunt is doing pushups and pullups in Paris while monitoring the action on his laptop. He's doing this so that the phone he's connected to back in Havana picks up his loud breathing and the CIA don't realise ahead of time that he's not in Havana at all.
- In Ilsa's compound in Casablanca, as Hunt and Benji walk in, there are two wetsuits hanging up — one in Hunt's size, the other in hers. She, or perhaps more accurately, Lane and the Syndicate, have already picked Hunt for the ledger heist, even if he doesn't know it yet.
- The plot of Puccini's Turandot, the opera seen in the film, concerns a princess trying to discover the name of a suitor, much the same as Ethan is trying to do for Ilsa and Lane at that point in the movie. To cap things off, a variation of 'Nessum Dorma' returns as Ilsa's main theme.
- Ethan dramatically knocks over the white box with Lane inside. In chess, White (the Syndicate) moves first, black (IMF) reacts. Checkmate.
