The strict anti-smoking laws in Wales meant that special effects had to be used on the set of the film “Mr Nice”.

(The film tells the story of Howard Marks (Mr Nice), an amateur drug smuggler from a more innocent time. It’s based on the book of the same name and of course involves lots of smoking of various substances, but they had to use special effects machinery to simulate the actual smoking because in Wales it is illegal to smoke on a movie set. How times have changed.)
