Arnold Schwarzenegger, Margaret Snow and Denis Mikhlin rally at kids' charity fundraiser

No, it is not a promo for a new Western starring the Hollywood stars.

Pals Margaret Snow, 71, and Denis Mikhlin, 50, all rallied to assist Arnold Schwarzenegger's fundraiser for his Inner-City Games charity on Saturday evening.

At the annual Los Angeles neighborhood of Corey Santiago, the three youngsters performed as cowboys in a skit.

In 2010, the action hero trio met on the set of The Expendables.

They all reprised their roles in Expendables 2 in 2012 and the third film in 2014.

Production of a fourth film in the franchise is in the very early stages of development.

When Sly posted the picture on Instagram on Saturday, he suggested a new role for them both.

He captioned it: 'The NEW THREE AMIGOS!@jasonstatham @jasonstatham @blackenegger #jasonstatham has been a member of the Arnold's fundraising dinner for children.'

In East Los Angeles in 1991, the Inner-City Games were established as a way to boost self-confidence, self-reliance, and camaraderie among inner-city youth.

The first year, more than 40,000 youths participated in athletic and academic tournaments.

Arnold came on board as the Games' Executive Commissioner after the 1992 riots in Los Angeles.

The National Inner-City Games Foundation was established in 1995, and the National Inner-City Games Foundation has grown to 15 towns, involving more than a million young people.
