Sylvester Stallone and Arnold Schwarzenegger have both dominated the action world for years, but when Arnie turned Governor, it seemed an onscreen duo was less likely.

When 'Expendables' came out, Schwarzenegger had a cameo role in the film, but the actor disappointed fans with his two lines of dialogue.

Bruce Willis also featured in a cameo but is set to have a bigger role in 'Expendables 2'. Will Arnie be tempted to go all out with Stallone in the sequel or another film?

The onscreen duo is not impossible to achieve, but the two actors have never had a bromance to the likes of Geroge Clooney and Brad Pitt.

Stallone continues to focus his career on action but admits that he will turn more to writing and directing as he grows older.   Schwarzenegger on the other hand still has the political ties, public speaking and book writing enthusiasm that could delay a comeback.
