Viewers who can't wait for the sixth season of "Mad Men" to arrive can console themselves with the season premiere of "The Hour" (9 p.m., BBC America, TV-14). Set in 1957 in the London studio of a struggling news program, "The Hour" is filled with period fashions, habits (smoking and drinking) and
attitudes (sexism galore and adult-
ery). Much like Peggy on "Mad Men," news manager Bel Rowley (Romola Garai, "The Crimson Petal and the White") is a competent woman overlooked and disrespected by the males in upper management. This second season brings the prickly and eccentric new head of news, Randall Brown (Peter Capaldi, "The Thick of It"), who im-
mediately destroys any vestige of Bel's authority.
It also marks the return of Freddie Lyon (Ben Whishaw, "Skyfall"), a slightly dreamy and idealistic visionary who sees their program, "The Hour," as a place to break rules and push boundaries. His co-host, Hector Madden (Dom-
inic West, "The Wire"), a glibly charming alcoholic, uses his television celebrity as a means to pick up women and cheat on his gorgeous and
"The Hour" puts even more emphasis on historical background than "Mad Men." The first season took place against the backdrop of the 1956 Suez crisis, while the second puts emphasis on nuclear fears and Britain's uneasy acceptance of nonwhite immigrants from the colonies.
Television shows that are about television can get a tad insular, if not dull. The writers have wisely chosen to explore the demimonde of Britain's criminal element and the
authorities who overlook and enable their activities. Hector's boozy stumbling offers a
dramatic keyhole into this world of vice, and his character does not get away unscathed.
"The Hour" will appeal to patient viewers. It takes a bit getting used to, particularly the accents and slang. At first, I thought subtitles might be in order. But acquired tastes are often the longest lasting and most satisfying.
