I recently saw the two Magic Mike movies. The first one is better than the second one. Of course they're not master pieces of cinema, but for what they are, they are good. And Channing's acting was pretty great IMO, he just seemed so natural and real. Now that I've actually seen him acting, I think he can deliver a believable performance.
On another note, it seems filming will start on November 9th:

Too bad, I thought it'd be in October. Another month to wait :-(
