Robert Redford at the 2013 Cannes Festival (French: Festival de Cannes), where "All Is Lost" was screened out of competition (i.e., did not compete but was projected, along with 20 films competing for the Palme d'Or, in the Théâtre Lumière)
Of his taciturn character, referenced as Our Man in the script, Robert Redford shares: "It's a challenge that attracted me a lot as an actor. I believe in the role of silence in film, and in life, because we often talk far too much."

Most of "All Is Lost" was filmed in Baja California's Baja Studios, where the water set was built by James Cameron for marine effects for 1997 blockbuster film "Titanic".
Included among three giant water tanks accessed by J.C. Chandor for "All Is Lost" is world's largest (= three football fields) infinity-edge tank, sited on the ocean shore.

Dubbed as Our Man (Robert Redford), the only character in All Is Lost is not lost, for he knows his location, but is lost, for he seems to have no more options.
"All Is Lost" captions the location of the film as in the Indian Ocean, "1700 nautical miles from the Sumatra Straits."
