Walbrook began in the 1930s in lots of Austrian and German films including the first version of VIKTOR UND VICTORIA, MICHAEL STROGOFF and as Prince Albert opposite Anna Neagle in those two Queen Victoria films VICTORIA THE GREAT and 60 GLORIOUS YEARS. He is also the evil mastermind in the first GASLIGHT and other classics like THE 49TH PARALLEL and Powell's THE LIFE AND DEATH OF COLONEL BLIMP. I must catch up with Powell's OH ROSALINDA! where he stars. He later appeared in the '50s as Ludwig of Bavaria in Max Ophuls' LOLA MONTES and of course in Ophuls' LA RONDE and in I ACCUSE, and later television work including as Waldo Lydecker in a German version of LAURA!
He has a simple grave in that actors' churchyard at St Johns church in Hampstead, London, a lovely 18th century spot, just opposite Kay Kendall. It says "Anton Walbrook, Actor". How very appropriate.
