So you have just been to the movies and your hero has been up there on the big screen looking really cool and fantastic, doing all sorts of amazingly athletic stuff, getting on with great looking girls or guys and then… he or she lights up a cigarette! How un-cool is that??
Well let's get real here
A smoker wouldn't have the breath to do all that athletic stuff.
A smoker would smell like a dead ashtray, so what gorgeous girl or guy would want to be close to that?
A smoker would not have great skin and hair.
It is more than likely that the actor or actress doesn't smoke in real life, because they have to look after their bodies to be able to get parts in movies where they can look fantastic, do all that athletic stuff and look good enough for it to be believable that they would 'get the girl/guy' who looks so amazing.
Tobacco companies sponsor movies, and demand 'product placement' because they are not allowed to advertise their products any more – and they really want to get people to smoke so that they can sell their product! 'Product placement' means getting their product seen in the movie rather than in a separate ad.
