The Untouchables might have a somehow, albeit slight, resemblance to The Expendables' theme, but it's in noway as bad as it. The latter tried way too hard to assemble popular figures and pull out a 'bad-ass' movie, but failed miserably, at least that's how I see it.
Al Pacino is just incredible. I watched The Godfather trilogy a few years back, and I was amazed, especially by the first and second part; the third series was okay, but not as good as the first two. Today, I watched his movie Surface and I also want to watch Heat, which I have been getting mixed, convoluted opinions on it. But I'm guessing a combination of Al Pacino and Robert De Niro cannot go wrong!
Also, a tidbit:
Not much of a fan but this looks cool. I watched the previous movies.
