Continuity mistake: When Fred kicks the beach ball into the man's washing up basin, the ball is all wet and covered in bubbles. When the man throws the ball over the next door neighbour's caravan and falls into their salad bowl, the ball is now clean and dry.
Audio problem: As Fred and Ernie are driving away from the butcher's shop (as the wives shout after them about them "taking care of their rods") you hear Fred laughing but his face is deadly serious.
Audio problem: In some scenes of the myna bird talking, its beak is not moving in sync with what it says and in other scenes it is.
Continuity mistake: After Professor Crump and Professor Vooshka have finished inspecting the mosaic at the bottom of the cesspit, Professor Crump helps Professor Vooshka out of the pit. Initially Professor Vooshka starts out of the pit by leading with her right leg, but in the next shot, she is leading with her left.
Revealing mistake: When Fred and Ernie are checking for signs of life on Professor Crump whilst he is lying in bed unconscious, the 'unconscious' Crump blinks and moves his eyes several times.
Continuity mistake: When Ernie tosses the burnt sausages out of the caravan, he tosses them out of the back window. When we see the dog eating the sausages, he is eating them by the caravan door.
Continuity mistake: Before the chicken is run over by the archaeologists' van, the appearance of the chicken changes between shots.
Visible crew/equipment: When Professor Vrooshka visits Arthur's caravan and asks him if he has any crumpet, you can see the reflection of the boom operator on the front door window behind her.
