Gooooo-devening. Toby Jones’s take on Alfred Hitchcock will probably be forgotten, now that Anthony Hopkins’s big screen version has opened. And that is too bad, because he delivers a potent performance as Hitch in this small HBO movie. The focus of the plot is his increasingly sadistic obsession with Tippi Hedren (Sienna Miller, above with Jones) during the making of “The Birds.” Some have complained that the story isn’t true (Hedren stands by it). But Jones is remarkable nonetheless. His Truman Capote in “Infamous” was similarly overshadowed by Philip Seymour Hoffman in “Capote.”

Finally, this season has taken off. I was concerned about the post-Jimmy era, but the past few episodes have filled the gap. Wisely, show creator Terence Winter has started to give Jack Huston’s Richard Harrow (above) some plot space. I loved watching Richard kiss Julia last week; for a moment, the camera showed him from his mask side, and he looked inhuman. The image drove home the fact that he’s a split personality. On the one hand, he’s a tender gentleman, and on the other he’s a cold killer.
