Gangs of New York 8 p.m., BBC America

I’m mentioning this Martin Scorsese movie for the same reason BBC America is airing it tonight: To prepare you for “Copper,” an extraordinary new BBC America police drama that premieres on Sunday at 10 p.m. Like “Gangs,” “Copper” is about urban crime in New York in the mid-19th century, with Irish gangs fighting violently for survival and dominance. The dark, suspenseful, and brilliantly designed period show, co-created by Tom Fontana (“Oz,” “Homicide”), is the first new scripted series from BBC America, and it bodes well. More on “Copper” later. Pictured: Leonardo DiCaprio in “Gangs.’’

Oh Sit! 8 p.m., Channel 56

Oh . . . wow. I almost misspelled that one. The original name of this show was “Extreme Musical Chairs,” and it brings back nightmares from the birthday parties of my childhood. But the clips make it look as though the show is going to be musical chairs on steroids, with obstacle courses and other “Wipeout”-like whatnot. Jamie Kennedy and Jessi Cruickshank cohost. What’s next, “Go . . . Fish”?

I Married a Mobster 10 p.m., ID

Or close enough. Whitey’s ex-girlfriend, Lindsey Cyr.

American Hoggers 10 p.m., A&E

This new show sounds (you know I had to) boaring.

Top Chef Masters 10 p.m., Bravo

They make salad for the B-52s. Romaine, if you want to.
