Withnail & I (1987)

Continuity mistake: When driving to Penrith, there is a shot of the road taken from the driving seat of the car. There are two headlight patterns on the road, but the car only has one headlight. (00:33:00)

Withnail: I've some extremely distressing news.
Marwood: I don't want to hear it. I don't want to hear anything. Oh God, it's a nightmare, I tell you, it's a nightmare.
Withnail: We just ran out of wine. What are we gonna do about it?
Marwood: I don't know, I don't know. Oh God, I don't feel good. My thumbs have gone weird! I'm in the middle of a bloody overdose! Oh God. My heart's beating like a fucked clock! I feel dreadful, I feel really dreadful!
Withnail: So do I, so does everybody. Look at my tongue, it's wearing a yellow sock. Sit down for Christ's sake, what's the matter with you? Eat some sugar.

Trivia: The bottle of lighter fluid Withnail drinks had been filled with water throughout rehearsals, but for the actual take was filled with vinegar, unbeknownst to Richard E. Grant, who plays Withnail. The director made the switch to get a good reaction from him.

Question: At the pub in London, on Marwood returning from the toilet and saying "balls to Monty", Withnail says he's just spent an hour on the phone to Monty "flattering the bugger"? Surely Marwood wasn't in there for an hour and it's unlikely Withnail would have had time to phone Monty in the short while he surely must really have been in there, especially with a threatening guy sitting outside and likely to come in the longer he spent there.
