Ever since Frank Sinatra christened Marlon Brando "Mumbles" on the set of Guys and Dolls, inarticulate and incomprehensible speech has been a mainstay of American cinema, particularly among Method actors. David Jenkins of The Guardian has had enough, and it's Philip Seymour Hoffman who has pushed him to the breaking point.

Jenkins' snippy piece begins: "So there they are, Philip Seymour Hoffman and Albert Finney, emoting like nobody's business after they've buried the woman who was, respectively, their mother and their wife, in Before the Devil Knows You're Dead. There's a silence, and then Hoffman speaks — whereupon Finney slaps him. It's clearly a crucial moment, this explosion of violence, but I've yet to talk to anyone who could hear what Hoffman actually said."

Jenkins goes on to bemoan the mushmouthed stylings of the cast of Charlie Wilson's War (including Hoffman again), Miami Vice (with non-American Colin Farrell cited as a prime offender) and even There Will Be Blood. (He lets the Coens off the hook, noting critic Anne Billson's explanation for the clarity of speech in No Country for Old Men: "The Coen brothers are famously proud of their dialogue, so they make sure you can hear it."

The piece traces screen mumbling back to Brando, of course, but also pins some of the blame on Robert Altman for his trademark overlapping dialogue. It's a little hard to believe that nearly forty years after MASH critics and filmmakers could still be uptight about Altman's brilliant cacophonies, but Sexy Beast producer Hercules Bellville agrees. "I've got no problems with 1940s films; then only Peter Lorre had a strange accent. Now there are all sorts of odd accents and dialects, and the colloquial is often rapid and slurred. But technically, there's no reason for it."

These guys are way too uptight; after all, it's not as if American audiences have never had trouble deciphering British speech, and you don't hear us complaining. To quote Benicio Del Toro in The Usual Suspects, "Gbaughg thfllwoogha schwfjflhaw."
