Scary television dramas never die, they just end up in repeats. Or, in the case of “Wolf Lake” (8 p.m., UPN), they get reincarnated on a new network. CBS canceled this spooky drama last October after a limited run. UPN will repeat the “Wolf Lake” pilot tonight and air five additional, never-before-seen episodes.

Starring Lou Diamond Phillips as a detective who scours a town infested by werewolves, “Wolf Lake” averaged six and a half million viewers last autumn. Those numbers may have been too small for CBS, but they would be nice for UPN, its corporate cousin. Last week, that network’s highest-rated show was “Buffy the Vampire Slayer” with about five million viewers.

Viewers can expect more of this network cross-pollination. A few years back, NBC and PAX shared the New Age detective series “Mysterious Ways.” On New Year’s Day, ABC wisely scheduled a marathon of “Alias” on its newly acquired ABC Family Channel. The stunt increased awareness and audience size for the stylish thriller.

The ambitious documentary series “Commanding Heights” (8 p.m., PBS) offers viewers an explanation of the global economy, its painful evolution and many critics. Shot on five continents over two years, “Heights” includes interviews with Vice President Dick Cheney, former President Bill Clinton, Mexican President Vicente Fox, former Soviet leader Mikhail Gorbachev, Singapore’s Senior Minister Lee Kuan Yew and former Treasury Secretary Robert Rubin.

Tonight’s installment chronicles the century-long debate between proponents of free markets and champions of government control and regulation. Next Wednesday, the series examines the painful adjustment to free markets, particularly in the former communist republics of Russia and Eastern Europe. Part three which airs on April 17 examines the recent emergence of a truly global economy and some of its downsides, including the fear of rapid global economic collapse and the violent debate over globalization that surfaced in Seattle a few years back.
