Sylvester Stallone's neo-Western finale to the 'Rambo' franchise is moving ahead and has officially gotten itself a title and added Mexican actor Paz Vega to its cast.

The fifth and probably final installment of the franchise will be titled 'Last Blood', with Paz Vega playing a Mexican journalist who teams up with John Rambo to help track her half-sister who's been kidnapped by a drug cartel.  The half-sister is also the daughter of John Rambo's friend, who also lives near the US-Mexican border.

Paz Vega's best known for her starring role in Julio Medem's 'Sex and Lucia', which became a crossover hit with audiences. Since then, she's turned up in 'Kill The Messenger' alongside Jeremy Renner and Netflix's 'The OA'.

The movie is now currently in production, with Bulgaria and Spain doubling for Mexico and the US, although no release date has been confirmed as of yet.
