BD was fortunate to see Treacle Junior at the London Film Festival last week - http://www.imdb.com/title/tt1542486/

It features our own Horniman Museum and one scene very close to the Moore Park Tavern.

Sadly I couldn't stay for the Q and A afterwards with the production team and cast to ask them whether Entertaining Mr Sloane was an influence.

You get an interesting image if you search "Treacle Junior" on Google images - features the main actor, Aidan Gillan, in a previous acting role. He's quite famous, don't you know.

Apologies for being so left field.
