The Lavender Hill Mob (1951)

Continuity mistake: Early on in the film Alec Guinness is travelling in the back of a van transporting gold bars to the bank. He spots what he believes is a suspicious car following and asks the driver to stop to check it out. The next shot shows the van stopping outside a row of buildings in a London street. The driver gets out to let Alec Guinness out of the van and they are now parked by a low wall with an open vista (probably one of the many bomb sites in London at the time) and no buildings.The next shot then shows the van outside the buildings again.

Neighbor: Ah, Holland, heh heh, the man of millions! What'd you get away with today? Got any spare ingots for an old pal? Ha ha, you'll be the death of me, Holland.
Henry Holland: I sincerely trust so.

Turner: Paris, eh? You're stepping out, Holland. Wonderful, isn't it, what a little extra money will do?
Henry Holland: Yes, it's going to make a big difference to me.

Pendlebury: Of all sad words of tongue or pen, the saddest are these - it might have been.
