This straight-up biography of the 17th-century painter starred Charles Laughton and was directed by Alexander Korda, a pair also involved in another biography higher up on the Internet Archive Top 100.
In giving it 3½ stars, Leonard Maltin praised Rembrandt’s “visual tableaux” and Laughton’s performance. Time Out magazine wrote that it was “less successful at the time” than that movie I hinted about “but a far better film”. You should watch and judge for yourself.
