In the opening scene Alf's shaving cut tissue paper moves position from the side of his mouth to under it.
When Rita reads Alf's "Daily Mirror" the headline reads "STAY IN JAIL TILL YOU DIE" (from Saturday 16th October 1971) - yet when he reads it the front-page story is now "WILSON CALLS HEATH A LIAR" (from Wednesday 13th October 1971). The "IS OLEG A PHONEY?" issue of Friday 1st October 1971 is also being read in the film, which is said to take place over six consecutive days.
