James Purefoy stars as Lucas Denmont in CBC's Diamonds.

The CBC surely would like to find a few diamonds to help ease its much-publicized budget woes.

But for the time being, the public broadcaster will have to make do with the mini-series Diamonds. Part one airs tomorrow, with part two a week from tomorrow.

Developed and commissioned by CBC, Diamonds is set in several continents and was filmed in three of the world's most exotic locations -- South Africa, London, England and Churchill, Manitoba.

Diamonds traces the morally questionable international web that brings us these fascinating gems. The fictional tale focuses on the Denmont Corporation, which has its headquarters in South Africa and is threatened by an upstart rival in the Canadian Arctic.

Diamonds stars James Purefoy, Joanne Kelly, Judy Davis, Derek Jacobi, Louise Rose and Stephen McHattie.

Diamonds has been sold to ABC for future broadcast in the United States.

Courts and courtrooms: Inspired by a high-profile custody battle, the made-for-TV movie Playing for Keeps airs tomorrow on CTV. It pits a young, white, female sports groupie against a married, black, pro basketball player and stars Jennifer Finnigan, Doug Savant (who plays Tom Scavo on Desperate Housewives) and Roger Cross.

More Treatment: The second season of the intense In Treatment, with Gabriel Byrne as Dr. Paul Weston, debuts tomorrow on HBO Canada.

The unique format for the series -- five half-hour episodes per week -- will get a new twist this year, with two new episodes airing consecutively on Sundays, and three new episodes airing consecutively on Mondays. And prior to the three new episodes on Monday, the two episodes from the previous night will be repeated, so if you want, you can watch five episodes in a row every Monday.

Other cast members this year include Dianne Wiest, Toronto native Alison Pill, Hope Davis and John Mahoney (who played Martin Crane on Frasier).

We'll always have Tara: The season finale of The United States of Tara airs Monday on The Movie Network and Movie Central. As great as Toni Collette has been playing a woman with multiple personalities, we think the series really has been stolen -- in a good way -- by Tara's two kids, played by Keir Gilchrist, a Toronto native, and Brie Larson, who has family roots in Canada, too.

Boob tubery: The new Bob Saget sitcom Surviving Suburbia debuts Monday on Citytv and ABC ... Christopher Plummer stars in a production of Stratford's Caesar and Cleopatra tonight on Bravo ... Saving Luna, a documentary about a baby killer whale who was separated from his family and went looking for companions, airs tomorrow on CBC Newsworld.
