Award Snub: The film received four Academy Award nominations and won three - Best Art Directing, Film Editing and Original Score. Errol Flynn wasn't nominated for Best Actor, its cinematography wasn't nominated and the reason Michael Curtiz wasn't nominated for Best Director is that he was up for Angels with Dirty Faces (though there were actually a number of write-in votes for his direction for Hood).
Awesome Music: Doubling as well as Awesome Music Of Crowning, the "March of the Merry Men," as it recurs in the coronation scene, is a riot of trumpet fanfares, soaring violins, and glittering harp strings.
Despite being called the definitive adaptation, there are naturally those with opinions on other adaptations such as Robin of Sherwood being more worthy of that title and that is all that need be said.
Likewise with Errol Flynn, one example being Brian Bedford. Again, that is all that need be said.
Catharsis Factor: The scene where the merry men ambush, outwit, and humiliate Sir Guy while robbing the treasure wagon in the forest is very enjoyable to watch.
Esoteric Happy Ending: Prince John is banished in the end, but he will become King of England upon Richard's death and his reign will be the beginning of the end of the Angevin Empire.
Evil Is Cool: The film's take on Sir Guy of Gisbourne is one of the most well-known and beloved takes on the villain to date, due to him having a pivotal role in the story this time around, and not being afraid to get his hands dirty in combat. The swordfight he has with Robin Hood in particular, is one of the most iconic filmed duels of the era.
Fair for Its Day: Marian is the one who comes up with the plan to rescue Robin. A female being credited with a plan to rescue a male was rather progressive for 1938.
Genre Turning Point: Before this film, historical movies tended to be written with a ton of Purple Prose. The original script was reportedly one of the worst cases of it ever and was totally rewritten with more natural-sounding dialogue, leading to the practice's being very quickly abandoned once its success became clear.
The opinion has been expressed that it pales in comparison to actual adaptations of the novel. Currently, The Adventures of Robin Hood has an I M d B rating of 7.9, while Ivanhoe (1952) has a rating of 6.8 and Ivanhoe (1982) one of 6.7.
Tough Act to Follow: For many this is the definitive film version of Robin Hood. Even with some later adaptations having become well-known in their own right, many fans still prefer this one.
