This aged take on the popular novel of a foppish English hero saving aristocrats from the guillotine during the French Revolution is an absorbing British movie; benefiting in particular from the excellent performance of Leslie Howard (one of England's greatest screen actors, despite his Hungarian ancestry), who gives the character of Percy Blakeney a humour and charm lacking from other actors who have attempted the part.
Merle Oberon also does well as his French expat wife - perhaps her best acting, even surpassing her later work opposite Olivier in 'Wuthering Heights'. Given that Howard and Oberon had a real-life love affair which started during this movie, it is interesting to note there are definite sparks between the pair on screen. Other actors in the cast are good value; Raymond Massey as the arrogant French ambassador who never thinks he can be outwitted; and Nigel Bruce, beloved later in the decade as Dr Watson, as the dullard Prince of Wales.
