London, Aug 8 (IANS): Hollywood action star Sylvester Stallone has revealed he used to consider fellow actors Bruce Willis and Arnold Schwarzenegger his "enemies".

The "Rambo" actor admits he used to get "jealous" if one of the other action heroes landed bigger or better movie roles than him, but claims their rivalry made them better in their careers, reports contactmusic.com.

"I was very competitive with them, and very jealous if they got a better movie or script than me. That's what made us push so hard. That's what made us push so hard, and it's why Arnold was so great," he said.

"He was far more diligent than me; I was too reckless. He's very machine-like and I did consider him an enemy. But, looking back, it was a good enemy," he added.

However, the trio are now set to be seen together in Stallone's upcoming directorial venture "The Expendables".

"I had written Bruce and Arnold into the movie in two different scenes but, to give Bruce credit, he said, 'Why not put us in the same room'. If you're going to get away from 'Rambo', you have to have that touch of humour in there," he said.
