While rolling the remaining barrel of cash, Walt passes the same pair of pants that he lost in the pilot.

In an interview, director Rian Johnson revealed that baby Holly's saying "mama" in the scene where Walt changes her was unscripted. The scene was written to have Walt simply look at Holly and decide to give her back. However, the baby's mother was on set behind Bryan Cranston, and the baby started saying "mama" while they were filming. Cranston simply went along with it and the shot ended up in the episode.

The flashback of Walt and Jesse at the beginning of the episode was the final scene that was shot for the series.

Series creator Vince Gilligan said in an interview that, "Ozymandias is the best episode we ever have had or ever will have."

This episode is considered by many television critics and audiences to be the greatest episode of TV ever produced. It received universal critical acclaim, is the highest rated TV episode on IMDb and won three Emmys for Best Writing, Best Actor, and Best Supporting Actress.

Guillermo del Toro desperately wanted to direct the episode "Ozymandias". When he expressed this desire to the episode's eventual director Rian Johnson, Johnson responded, "Yeah, sorry, I'm the one who gets to f*** the prom queen."

The episode's title gets its name from the famous poem by Percy Bysshe Shelley, which alludes to a crumbled empire. Bryan Cranston read the poem in a promo for season 5B.

Vince Gilligan requested, and received, permission to not show the traditional opening cast and crew credits until over 1/3 of the episode was shown, because he felt the titles would take away from the shock and horror of the events that were shown (both the flashback to the first time Walter White and Jesse Pinkman cooked meth in the desert, and in the moments after the shootout between Hank, Gomez and Uncle Jack's gang).

The knife Skyler picks up is the exact same one that Walt uses in season two, fearing that Tuco would come to the house.

Ozymandias is the only TV show episode that has recieved a 10/10 user rating for over a year. It had maintained a 10/10 rating for almost 4 years, and despite lowering to 9.9, as of November 2020 it is back up to its original perfect score of 10/10.

This episode is rated 10.0 by over 110000 votes.

This episode was both Anna Gunn and Bryan Cranston's submission tape for the best Supporting Actress and Lead Actor in a Drama Series categories in the 2014 Emmy Awards, respectively. Both of them won in the nominated categories, being Cranston's fourth win for Breaking Bad and Anna Gunn's second.

There was another director attached to helm this episode, but when he/she couldn't do it, Vince Gilligan quickly got in touch with Rian Johnson, who had expressed the desire of doing another episode before the show was over.

Rian Johnson directed this, the most popular episode (highest rated); and he also directed Fly, the least popular episode.

The final shot of the cold opening of this episode, where Walt and Jesse are shown cooking their first batch of meth, shows them and their RV fading away, leaving just a vast desert landscape in frame. The last lines of the poem Ozymandias, which this episode is named after, describe how a vast desert landscape is all that remains of a once mighty empire.

The episode won an Emmy Award for Outstanding Writing for a Drama Series.

Aaron Paul (Jesse) & Jesse Plemons (Todd) also worked together on episode 4.1, Black Mirror: USS Callister (2017), of Black Mirror (2011) as Gamer691 & Robert Daly respectively.

In the fire station, we see someone move the white king piece in a chess game. In chess, moving the king is a method of (temporarily) avoiding a loss when the player is under direct attack. Although this episode's title references a fallen king (Ozymandias), this chess move symbolizes that Walt (the white king!) prevented his own downfall and that he isn't finished just yet.

The fire station that Walt leaves Holly at is actually five miles north of the actual White residence.

There are many visual callbacks to previous episodes in this one: Walt's shocked, agonized reaction to Hank being shot is identical to Gus's shocked, agonized reaction to the shooting of Max in episode 4.08, Breaking Bad: Hermanos (2011); Walt sees the pair of pants that he lost in the desert in the Pilot; Skyler's accusation that Walt killed Hank is nearly identical to her telling him, "I f***ed Ted" in episode 3.03, Breaking Bad: I.F.T. (2010); Jesse's beaten, pulpy face is similar to Gus Fring's face at the end of episode 4.13, Breaking Bad: Face Off (2011); After his call to Skyler, Walt breaks his phone in half exactly like Gus Fring did in episode 3.08, Breaking Bad: I See You (2010).
