In the 2012 Kino Lorber remastered DVD, the English subtitles have some errors. In episode 8, "The Lord of Thunder", Satanas intends to rescue Irma Vep from a prison ship bound for Algeria. Disguised as a priest, he passes her a coded message which rearranges into "Le navire sautera". Colloquially, this means,"The ship will blow up", but the subtitle translates this as "Jump overboard"; probably a good piece of advice anyway, as he does arrange to explode the ship.
Later on in the same episode, Satanas plants a bomb in Guérande's apartment, and tells the paralyzed reporter that "the house will jump in five minutes"; same mistranslation.
