Paradise Towers: | ||
 | ep 1-4 – | The elevators in Paradise Towers commit an error common in television programs that use lifts: the lift door is depicted as just a single sliding door. In reality, lift doors are always double — an outer door on each floor, and an inner door which belongs to the lift compartment itself. |
| ep 1 – | The cake Mel is eating suddenly vanishes when Pex bursts into Tilda and Tabby's apartment. We see her put her cup and saucer down, and move as if to put the cake on the table, but in the next shot there's simply a completely empty plate sitting on the table... |
| ep 2 – | The Doctor twice states that the coins he finds bear the inscription "Issued by the Great Architect, Kroagnon". However, when we see a close-up of one, it simply reads "Issued by Kroagnon". |
 | ep 3 – | When Tilda throws a knife at Pex, the string holding it up is painfully visible. |
| ep 3 – | The cleaner carrying Tilda's body to the basement bumps the wall slightly as it goes through the door. |
| ep 3 – | In Tilda and Tabby's apartment, Mel tells Pex they are on floor 109. Yet, as we saw earlier, the number of the apartment (on the wall outside) is 1236. It would be very unusual (not to mention confusing for the inhabitants) for a high-rise building not to incorporate the level number into the apartment number. |
| ep 3 – | On a similar note, when Mel and Pex get into the lift, the indicator initially reads 48 — hard to believe they climbed down over sixty floors from Tilda and Tabby's apartment before thinking to use a lift instead! |
| ep 4 – | When she is attacked by the pool cleaner robot, Mel (or rather her stunt double) is completely submerged underwater at least three times. Yet in the intercut reaction shots of Bonnie Langford, and when she's talking to Pex after the attack, most of her hair is still dry. |
