London: Critics say that "Rambo 4" starring Sylvester Stallone, who has also directed it, is the most violent movie of the series with over two deaths a minute.

The movie is just 93 minutes long but has 236 killings. That is 2.59 every 60 seconds.

Mirror.co.uk quoted film critic Mike Thomas as saying: "Beheadings, disembowelment, exploding bodies, raping, torturing... it's most likely represented."

The first instalment of "Rambo" in 1982 had just one death.
