Written by Moira Walley-Beckett and directed by Michelle MacLaren, it aired on AMC in the United States on September 2, 2012.

The episode is named after poem 271 in Walt Whitman's Leaves of Grass, a book that is featured prominently in the series.

At Vamonos Pest, Walter White and Todd prepare a barrel of hydrofluoric acid to dispose of Mike Ehrmantraut's dead body.

After Lydia leaves, Walt removes his hat from the table, revealing a hidden vial of ricin presumably meant to poison her.

[2] Walt tells Lydia "Learn to take yes for an answer," which is exactly the same advice Mike gave him in the bar ("Thirty-Eight Snub").

[3] In "Ozymandias", Walt tells Jack Welker that the buried pile equals $80 million; however, Gilligan expressed his doubts during an earlier podcast:[4] "I asked prop master Mark Hansen, and he and his guys had tried, just for their own edification, to figure out how much that would be if it was roughly a half-and-half mix of twenties and fifties, and he guessed somewhere in the vicinity of eighty million dollars—eighty, eighty-five, ninety—that's a lotta dough.

"According to Peter Gould, the episode originally featured a scene where Walt is told by his doctor that his cancer is still in remission.

[6] TV Fanatic's Matt Richenthal gave it a 4.8 out of 5 star rating, stating: "'Gliding Over All' still managed to shock, taking Walt to a place I never imagined he'd be prior to the big reveal: contentment.

[7] Alan Sepinwall of HitFix called the episode "an absolutely gorgeous piece of work, in both the visual sense and the way it brought us to the next, final phase of Walter White's story.
