During the balcony scene, Cyrano's white plume is dark.
In the film's opening scene, after Cyrano starts to leave the theatre along with the others, Roxane bids good night to DeGuiche and Valvert and seems to exit, but moments later she is seen watching Cyrano's duel in the theatre though she has not been seen to re-enter.
When Cyrano fights off "100 men" to save Ragueneau, a stunt double can be seen in some shots doubling for José Ferrer.
