Though filming has been underway for quite some time now, the casting additions to Christopher Nolan‘s The Dark Knight Rises seem to keep piling up in droves. Most recently was last month’s announcement that Adam Rodriguez, perhaps best known for his work on CSI: Miami, would be joining the crew. It doesn’t look like Nolan and company are quite finished, though, as Rob Brown, the star of 2008′s moderately acclaimed but financially disappointing The Express, has also come on board the cast.

As you’ve probably heard countless times already, Nolan‘s group of performers for this installment — Christian Bale, Morgan Freeman, Michael Caine, Gary Oldman, Tom Hardy, Joseph Gordon-Levitt, Anne Hathaway, Marion Cotillard, and Juno Temple — is absolutely stacked. I have a sneaking suspicion, however, that the group of characters may be getting out of hand — how much ground, after all, is it possible to sufficiently cover in a single film? — but Nolan has never made a single misstep in his career so far, and it’s hard to imagine that he’ll start here.

The Dark Knight Rises will hit theaters on July 20th, 2012. Do yourself a favor — if you haven’t already — and simply try and tune out the plethora of on-set footage that’s been hitting the web. I haven’t given a single viral video an actual look since back when Bane’s costume was first caught on tape, and it just feels right.

Do you have any concerns about the ever-growing cast? Any thoughts on the addition of Brown?
