I have no problem with the casting of Mitchell or Henreid as Frenchmen, or Hans Conreid as a Gestapo agent. This was a generally engaging story of Allied flyers hiding out in German-occupied Paris in World War Two and their attempts to escape aided by Joan, played by the lovely and charming Michele Morgan. Watch for a young Alan Ladd in a small role. Stealing the show is the great Laird Cregar as the chief Gestapo agent. Cregar was a superb actor, but he must have tired of all the evil people he was forced to play owing to his weight; Henreid would get the girl and he'd get slapped. Cregar, a young man, went on a crash diet that apparently lacked needed nutrients - he died suddenly. And it was a shock and great loss to Hollywood, and to us all.
