DVD: A Royal Affair, For retail & rental (Metrodome) This rich, intelligent and moving Danish period drama tells the incredible true story of a German doctor (Mads Mikkelsen) who ministers to the mentally fragile King Frederick VI (Mikkel Boe Foelsgaard) and has an affair with Queen Caroline (Alicia Vikander) in late 18th-century Copenhagen. As much about social reform as it is about bodice-ripping, it deserves to be ranked alongside Amadeus and Dangerous Liaisons.
