Cary Fukunaga spent two years researching the film, spending time with people on the trains and with gangsters in Central America. He also used two gang members to script edit making the slang and language as up to date and realistic as possible.

The homemade gun, made of pieces of steel pipe, is called a 'chimba'.

The title "Sin Nombre" translates as "without a name."
