I love this movie, it has all sorts of really great lines in it! There are also, of course, a few mistakes.

In the famous street dancing scene, which is supposedly in 1967, you can see the curbs have modern forms to them. Also in this time period, the cop is wearing a riot hat, which did not exist.

Austin's aircraft is a Boeing 747 - which didn't exist in 1967.

In the opposite direction, the English soldiers in modern times are using SLR rifles, when they should have had SA-80 rifles.

Mrs. Kensington's car doesn't have a front license plate on it - this is a requirement for cars in Britain.
