I wouldn't argue against those guys, either, but I'm talking about the fact that film acting, as an art-form, has now evolved to the point, that even the most average actor today, can realistically hold a conversation, on film, that sounds like a real conversation. I'm wild about a lot of early film actors, but film, itself, wasn't as realistic then - it was closer to its stage roots, more melodramatic, so was the acting. I'm not saying it was bad. It just hadn't evolved yet. Look at James Cagney in "Ragtime." A wonderful, subtle performance. Modern acting in a modern film. The technique of other early Hollywood actors, who were still working in the 60's, were able to evolve as well. Any actor worth his salt, these days, should be able to realistically portray a character from the past, if he's done his research. Fortunately, the bar has been set so high, by people like Meryl Streep, Robert Duvall, Robert DeNiro, that an actor would be ashamed not to do their research.
