Almost two years after aquiring media firm Olswang, CMS is enjoying the stardust that comes with movie work. 

This week it informed the press that it had "advised on all legal aspects" of the development, financing, and distribution of the not-awaited sequel, Mamma Mia! Here We Go Again. The original earned tepid reviews ("The legal definition of torture has been much aired in recent years, and I take Mamma Mia! to be a useful contribution to that debate", raved the New Yorker). But it made boffo box office, taking in $615m on a $52m budget. 

Early reviews of the sequel, which stars Julie Walters, Pierce Brosnan, Colin Firth, Stellan Skarsgård, Meryl Streep and Cher, suggest it's better than the first. Not a high bar, but when all is said and done, does your mother know, Fernando, etc.

Mark Devereux, the ex-Senior Partner of Olswang and the well-connected media partner who ran the matter, said it was “great" to have "played a small part in what is bound to one of the biggest hits of the summer”. He played an actual small part in a movie in 2012, when the makers of Salmon Fishing in the Yemen included him as the British Prime Minister, albeit only in a photograph. It is not known whether he said "That's me", or "Why did it have to be me?" or some other Abba reference.
