A lovely moment from Claude Jutra’s À tout prendre (Canada, 1963). Johanne and Claude are in love and now a couple. He introduces her to his friends, which include François Truffaut. Johanne asks François to show her how to blow cigarette smoke out,  like in the choo-choo train scene in his Jules et Jim (France, 1962), which must still have been in release when this was filmed. The dialogue in English goes something like this:

Claude: ‘It’s odd but since I’ve fallen in love with you going out pleases me more even though there’s nothing to see.’

Johanne: ‘But there’s more to show’

Claude: ‘What?’

Johanne: ‘Me!’

Claude: ‘You!’

Johanne: ‘What?’

Johanne: ‘I find your friends wonderful’.

Claude: ‘No need to tell me I can see’.

Johanne: ‘They find me beautiful. They have such great taste that they all deserve a little hug’.

Claude: ‘There’s no need for that. Thank you very much’.

Johanne:Don’t be silly I adore you.

Johanne: ‘François? Show me the trick with the train smoke, you know? Like in your film?’

Truffaut: Oh it’s easy’.

Truffaut: ‘blow!’

Johanne:’Oh’

Truffaut: ‘Very good’
