Anatomy of an Episode: "Mother's Mercy"

The Real History Behind Game of Thrones
In a two-part
series, historians and George R.R. Martin discuss the era
known as “The Wars of the Roses" and other historical
events that served as inspiration for his novels.

Audio Commentaries
Twelve audio commentaries with cast
and crew including David Benioff, D.B. Weiss, Peter Dinklage,
Lena Headey, Kit Harington, Nikolaj Coster-Waldau, Iain Glen,
Maisie Williams, Natalie Dormer, Gwendoline Christie and more.

Four deleted scenes.

The behind-the-scenes featurettes for Season 5 - "New characters/
New locations" and the "A Day in the Life" production documentary.

Histories & Lore Season 5 - the next installment in the series
of animated featurettes exploring the mythology.

The Dance of Dragons - an "in-depth featurette" on the civil war
that tore Westeros in half 170 years before the TV series, in
which Targaryen fought Targaryen and dragon fought dragon (as
Shireen explained in episode 5.9) and backstory of Westeros and
Essos. The "Dance of Dragons" featurette is a super-sized animated
featurette, like the regular "Histories & Lore" series, but 20
minutes long to summarize the entire narrative of the civil war.
