London, May 1 (IANS) Actor Sylvester Stallone has started working on the fifth instalment of his blockbuster "Rambo" series.

The action star last reprised his role of the Vietnam veteran in 2008's "Rambo", and has revealed he's writing a draft for final instalment for his classic character to give him a fitting send off, reports express.co.uk.

"I know there is. It's one thing where you lay down the final culmination of your life where you can articulate it, but also act on it where he realises what his destiny really is. It's not to be a farmer, it's not to be obscure - it's to go out in a blaze of glory in a heroic fashion... That's who he is. I'm working on a formula for it right now," he told MTV.
