Movie poster art effect query

[JasonGreen]

Hi there, I'm new to the forum but could an expert tell me how this effect is achieved on movie posters?

What sequence of filters and effects are used if it is Photoshop? It almost looks like the photo of the people is a painting. The same effect is also used in the segent of the "National treasure 2" poster where the woman is running in front of the White House. It is a very ethereal effect that I would like to recreate but do not know how. Any ideas? Would be much appreciated.
And a happy New Year to you.

Your link sucks! It's brings up numerous pop-up ads!! Next time copy the picture and post.

That site always has those pop up ads.

But I would like to know about that effect as well.
