The U.N.C.L.E. Samurai Affair - S1-E27
Revealing mistake: Mark's stunt double in the final fight scene has a very bad (and obvious) brown wig. Mark's hair, however, is blond. (00:44:00)
The Prisoner of Zalamar Affair - S1-E2
Revealing mistake: Mark finds the bomb planted under his Jeep and puts it under the bad guy's car instead. When it explodes, there's a huge cloud of smoke, but before the shot cuts, you can see that the car is completely undamaged. (00:10:30)
Audio problem: When LeGallows complains that the road is unendurable, his lips don't move at all. (00:20:15)
