I went to the pictures to see
Tinker Tailor Soldier Spy, and although they didn't run the actual movie trailer for
Secret of 'The Unicorn', they
did play an adapted version as an advert for the Odeon Première Club (the chain's loyalty-card scheme): instead of the object dropping from the broken mast being a tube, it was a card which Snowy finds on the floor; when Tintin looks at the parchment through the magnifying glass, the wording is talking about scheme benefits.
The rest of the ad is accompanied by a voice-over talking about a competition they are running, which is based on a draw from people joining the scheme during a certain period.
The competition is
described on the Odeon web-site:
