Revealing mistake: When Rick realises his bedroom is on fire, he opens a window to allow water from a flood to come into the room and put the fire out. When the fire dies out as it gets covered in water, a digital red cloud can be seen around the fire as it goes out, revealing that the fire was a digitally added effect. (00:20:23)
Revealing mistake: The neighbourhood outside Rick's window is flooded and completely covered in water. When he opens the window and water comes into the room, the water shown outside the window appears to be a dark blue colour. But once Rick closes the window, the water switches to a light teal colour midway through the shot, revealing that the water is a digital green screen effect. (00:20:24)
Continuity mistake: When Rick closes the window after putting out the fire, there is a small fire behind his bed that hasn't been put out. Vyvyan then walks into the room and the fire behind his bed is suddenly out. Also, the bottom of the curtain next to the bed suddenly moves onto the windowsill in between the two shots. (00:20:27)
Revealing mistake: When Neil points to the window after saying he hates sharks, Vyvyan says, "That's just the most completely brilliant thing I've ever seen," whilst sharks are swimming past the window. Just as Vyvyan finishes the line, there appears to be a visible cut on-screen shown around the window, where the sharks are swimming past, revealing the use of stock footage of sharks swimming that was digitally added over the window.
