- Creator Backlash: Tom Cruise reportedly wasn't happy with the American cut of the film and wouldn't talk about Legend for years because of it. He very much encouraged fans to go with the Director's Cut.
- Cross-Cast Role: Meg Mucklebones is played by Robert Picardo.
- Cross-Dressing Voices: Gump is voiced by the actress who plays Blix.
- Dawson Casting: David Bennent was about 18 when he played the boy-elf Gump and Annabelle Lanyon, who played the faerie Oona, was about 24.
- Hey, It's That Voice!: Norio Wakamoto voices Darkness in the Japanese dub.
- Re Cut: The film came to theathers lasting 95 minutes (cut down further 6 for the US). The DVD uses an 113 minute "director's cut". Both have different scores (the Blu-Ray gives the option to use either Jerry Goldsmith's or the one by Tangerine Dream).
- Troubled Production: Given it's a fantasy film directed by Ridley Scott, a highly ambitious production ensued. With the inherent problems - an enormous make-up crew, Tim Curry injuring himself removing the claustrophobic prostethics too fast, the famed 007 stage where the film was shot burning down - and long production - Mia Sara came of age during the 3 years of filming! Also, during post production Scott came down to cutting the film profusely and change its soundtrack from Jerry Goldsmith's orchestra to Tangerine Dream's electronica (both were restored in the director's cut).
- What Could Have Been: Scott's film originally ran much longer and had a number of scenes deleted from it, at least two of which were not included in the director's cut.
- The first involved an alternate opening sequence wherein the goblins encounter the unicorns, represented as light beams, and report back to Darkness. For the most part, this sequence is uninteresting but for two elements: one, features four goblins (the fourth, Tic, comes to a bad end), and two, it explains why Blunder has a chicken foot for a left hand (Darkness changed it when Blunder spoke out of turn).
- The second is an extended version of the scene by Jack's fire wherein Gump is even less forgiving of Jack than in the director's cut, using his violin to magically force Jack to dance before making him answer the riddle. This explains Jack's sudden sweatiness and seeming exhaustion between shots in the finished version, and why Gump refers to him as "riddle-solver, dancing fool and faerie-friend". On the Blu-Ray the scene is represented by stills and storyboards over the surviving soundtrack. A couple of behind the scenes shots are also seen in the accompanying making-of documentary.
- There are also elements from the original script which Scott never even attempted, such as Lily's encounter with a "house brownie" (like the ones in Willow), Lily transforming into a humanoid cat creature, Darkness growing huge bat wings during his battle with Jack, a final revelation that Jack is actually immortal, and the unicorn taking Darkness down after the sun sets causing the light trick used to send Darkness to his doom fails.
