Not trying to pick it apart or inflate it. Like I said, it's only a WTF? because I read the original dialog in the leaked script. It's disheartening... had it been the intention all along I would have been "OK." I just wonder why they did it.
BTW, the guy doesn't really have a hispanic accent... not in that scene. That's a regular ol New York accent. It's obvious he speaks English perfectly and has no problem with it. Chic on "Without a Trace" (she's Puerto Rican off the boat), THAT's an accent. What's funny is that I just read the actor's bio, which says that after moving to New York he "trained at the American British Dramatic Arts School." Hollywood Shuffle, indeed (whoever hasn't seen that movie really should).
Anyhooo.... yeah, it's not a big huge deal. And like someone pointed out maybe it was the actor's idea (see Hollywood Shuffle, folks). Common Hollywood stuff. It IS an idiotically-stereotypingly scene. Could it be worse? Sure.
