When the video was first released, Ruggles Outbound was credited as "The Ghost of Stanley Kubrick" in the description of the battle.
The description has since been changed to credit him.
At a recent concert, EpicLLOYD said that Tim Burton almost made it into the battle.
This is currently the most viewed battle of Season 4.
On August 22, 2016, "Rap Battles are life with all the dull bits cut out." was written in the description of the video, followed up by the sentence "Season 5.5 is coming soon!". This is a reference to Alfred Hitchcock's quote, "Drama is life with the dull bits cut out".
Not including the recording sessions or green screen cuts, this is the third battle to have more than one Behind the Scenes video.
This is the sixth battle where one actor voiced/portrayed more than one rapper.
This is the third battle to have additional music added in created by the ERB crew.
This is the first time the creator of a character appears after the character, and the third instance a character and their creator have both rapped in the series.
This battle has the most beats out of any battle; at five.
This is also the first battle in which every rapper has their own beat.
This is the first battle where a character cannot be directly seen in their title card.
An early version of the video description was: "Directed by Woody Allen. Written by Martin Scorsese. Edited by George Lucas. Musical Score by Prince."
These credits were also posted by ERB in the comments of the video.
During Steven Spielberg's title card, he points out his finger and it glows, a reference to E.T.
In Alfred Hitchcock's title card, he is shown as a silhouette from the side, a reference to the intro of Alfred Hitchcock Presents. Later, both Spielberg and Hitchcock can be seen as silhouettes during the end of Spielberg's verse and start of Hitchcock's verse.
During Hitchcock's line "I'm the master…of suspense", the sound effect and the knife motion is a reference to the famous shower scene in his film Psycho.
Quentin Tarantino's background is a reference to his Kill Bill films. The promotional posters for the films often use the color yellow, black stripes, and blood splatter stain, and the character of the Bride wears a yellow jumpsuit.
Tarantino is dressed as his character Jimmie Dimmick from his film Pulp Fiction while saying the lines, "What's your favorite Sam Jackson part?" and "What's-his-name from Jurassic Park!", along with the ad-libs, "Fuck!" and "Dick!"
Stanley Kubrick can be seen riding a tricycle based on the one from his film The Shining during Quentin Tarantino's verse.
The last part of Tarantino's verse is intercut with brief shots of Kubrick riding a tricycle down the hallway of the Overlook Hotel. This is a reference to a scene from The Shining in which Danny Torrance rides his tricycle down the partially carpeted hallway, creating a brief rolling sound as the tricycle hits the wooden floor and a silence as it rolls over the carpet.
During the intro before Kubrick's verse, Kubrick can be seen holding hands with an identical twin of himself standing in the hallway of the Overlook Hotel. This is another reference to a scene from The Shining.
The music before Kubrick's entrance is Richard Strauss' "Also sprach Zarathustra", which was used as the theme of his film 2001: A Space Odyssey.
Kubrick's line, "Every single frame a painting made exactly how I wanna make it", references Every Frame a Painting, a YouTube channel about film techniques. This channel helped inspire the battle (confirmed in a comment by the ERB channel on one of their videos).
The colorful background that starts with Kubrick's line "Do another take and get it right, 127 times" is a reference to the Stargate sequence from 2001: A Space Odyssey.
In Kubrick's line "Like Clockwork, make you all hurt, beat Spielberg The Color Purple!", he points at his right eye, referencing his film A Clockwork Orange, where the main character Alex DeLarge wears makeup on his right eye.
During the "Who won? Who's next?" sequence, Hitchcock dances with his hands flapping like a bird, a reference to his film The Birds.
During the "Who won? Who's next?" sequence, Michael Bay dances as if he is starting a chainsaw, a reference to the remake of The Texas Chainsaw Massacre, which he helped produce.
During the end slate, Tarantino's dance is a reference to the dance John Travolta's character Vincent Vega did in Pulp Fiction.
Many references are made to common tropes within each director's works:
Spielberg: The dolly zoom (in his first four lines)
Hitchcock: Shot in grayscale like most films during his era
Tarantino: The trunk shot (at the end of his verse)
Kubrick: Long periods of silence (the intro leading up to his verse)
Bay: Explosions (throughout his verse)
At 0:19, the animation of the inside of the T-Rex's mouth glitches for a few frames.
Quentin Tarantino's opening line has a misspelled "Gimme," as it says, "Cut! Gimmie a Tylenol!"
During the line, "Ask anybody, 'What's your favorite Sam Jackson part?'", Tarantino's right hand gets cut off.
At 1:39, the blood spatter on the bottom left corner of the screen abruptly disappears.
During the lines, "I make that dollar, y'all, motherfucking money!" and "Got no time to read reviews while I'm working on the sequel!", Michael Bay's left hand gets cut off.
During Bay's verse, the subtitles say "got few a drops" instead of "got a few drops".
