Goofs

When Howard emerges from the study grinning, Daniel, Jane and Robert all turn around and stare at him in horror. Except that they wouldn't be able to see him. In the following shot, it is obvious that the view of the study door is obstructed by a wall.

Troy drops the bottle of 'Valium' on the kitchen table, label face up, to answer the door. His sister Martha walks by and the bottle is laying label face down.

When Daniel is giving his final speech about his father at the funeral service, at one point, Jane is seen in close-up, looking at him, however, in the very next shot, she is looking down at a photograph in her hand.

When Simon gets out of the bathroom window he is completely naked, but moments later he appears in the same position leaning over to spit and you can see the edge of his underwear at the bottom right of the screen.

During the commentary track Andy Nyman states that a driving scene prior to picking up Uncle Alfie was on the Westway in London and that they went past his Daughter's school. This is incorrect and it is actually on the A3 in Guildford, and the Cathederal (used in The Omen) can be seen in one shot too.

If Uncle Alfie was confined to a wheelchair, how did he get onto the roof?

When writing the cheque for Peter only his Christian name was known so he could not have completed the cheque. The character is in the credits only as Peter so the cheque could never have been valid.

Unless, of course, the cheque was made out to "cash". Then the name wouldn't matter.
