El Clan

Guillermo Francella is more well known in Argentina as a famed comedian, in contrast with the dark character he portrays in this film.

Scenes involving trains were filmed near the Urquiza line, the only one of the Buenos Aires metropolitan network using the same electric rolling stock from the 70s. However, in one scene a train passes by rightward and it can be seen it's painted mustard with a gray strip, which is the painting scheme of the current private operator and not of the former Ferrocarriles Argentinos. However, other scenes do show trains with the characteristic "colibrí" yellow-blue-red scheme.

Other than that, the rail tracks show Pandrol clips fastening them to concrete sleepers. Neither of those were used until the 2000s.
