Continuity mistake: Near the start when Albert is plating up the takeaway, you see him beginning to remove the lid from the takeaway. In the next shot however, the lid is completely off. The change in shot is immediate and there is no way that Albert could have moved it in that time.
Plot hole: When all the gang including Arnie leave the flat to go to the restaurant to meet Mr Stavros, Rodney decides to stay at the flat and wait for Cassandra to phone him. The next scene shows the gang all watching Arnie in the restaurant waiting for Mr Stavros to arrive. Rodney is sat in the van with Uncle Albert but Rodney decided to stay at the flat so there was no way of him being there.Joe Mc
Character mistake: During the scene of the dinner, James (Raquel's father) states that he was in the Royal Navy and was "First Officer" (1/O). The Navy does not have this rank since it is a Merchant Navy rank. The rough equivalent of this is Lieutenant in the RN and Albert would've known this but didn't mention anything. It is also extremely unlikely that an officer the RN would still be Lieutenant after doing his full quota of 12 years service.
