Flipper and the Bounty - S2-E13
Visible crew/equipment: After Bud wakes up all alone in Bligh's cabin, he soon realises all the doors are locked. Then, just as Bud rushes over to the stern window (particularly the second time), a seated crew member is visible at the bottom right corner of the screen; we can see the movement of a leg and two hands (so, it's not a mannequin).
Continuity mistake: When Flipper guides Rick to Bud's location, Rick carries Bud to the launch and hands him to Mr. Enfield, with Bud's head at Enfield's left arm. It cuts to the next shot, and now Bud is lying in Enfield's arms the opposite way, with his head at Enfield's right arm.
