The Wild Wild West (1965)

The Night of the Murderous Spring - S1-E27

Revealing mistake: Kitten bends apart the cell bars, allowing West and Gordon to escape. But when they brush against it on the way out, one of the "iron" bars gives, flexing like the rubber that it probably is.

The Night of the Murderous Spring - S1-E27

Continuity mistake: When Dr. Loveless falls from the sill of the double window, the right half of the frame is open (the camera view being from the outside looking in). When West rushes outside to find the "body" missing, the right frame has closed itself and the left is now open.
