Perhaps I should have bought it.
D was ranting on about the number of 'B' movies he was seeing being advertised. Even one that was called B movie, about a bee. I told him that it was years old. He told me that no - he had seen it advertised on the side of a bus today.
After a great deal of confusion it turned out D had seen an advert for the Transformers movie Bumblebee. Not for the Dreamworks Bee Movie.
I'm glad we got that sorted....
