Hollywood action titan Sylvester Stallone, who has shared screen space with his once rival Arnold Schwarzenneger in "The Expendables 3", says the latter is the reason for his "hard work".

At a recent event, Stallone got candid about his rapport with Schwarzenneger, said a statement.

He said: "We both are pretty similar. We worked together and came into the scene at the right time in the movie industry. Then I got older and wiser and realised - thank god for Arnold - he's the reason of my hard work."

The mega-budget actioner "The Expendables 3" will release in India Aug 15. It will be distributed by MVP Entertainment and PVR Pictures.
