The cigars themselves totaled a whopping $20,000 of the movie’s production budget, which isn’t small potatoes, even when you consider the film’s $30 million budget.
To give you a better gauge of exactly how much Gary Oldman was smoking during production, he says Darkest Hour went through at least 400 cigars.
We don’t see actors smoking nearly as often in films like we used to, but in the case of Darkest Hour it was accurate for the character of Winston Churchill to be smoking cigars.
Even if the cigar was partially “smoked” by the time it made its way into Oldman’s hands, that’s a lot of smoke to be getting involved with.
