Michael Jackson's second career really takes off this week

(MCT) — Like Elvis Presley, Jimi Hendrix, Bob Marley, Kurt Cobain and Tupac Shakur, Michael Jackson is just beginning his career as Pop Star Who Will Never Really Die.

His movie "This Is It," based on rehearsal footage for the tour he was supposed to begin in July, comes out Tuesday night, and his first posthumous album, the movie soundtrack, is also out. Four months after his death, he's one of the most active performers in the music business, and he's up for five American Music Awards, too.

MORE MUSIC: "This Is It," a lovesick ballad — co-written with Paul Anka — with slinky funk guitar and strings, is Jackson's first "new" song since he died. And it just happens to share a title with the movie. The song is actually one of the hundreds of unreleased tracks he left in the vaults, according to estimates from Sony Music executives, and surely just the beginning of a flood of new releases. Before his death, Jackson recorded with R&B star Akon and the Black Eyed Peas' will.i.am, among other hot producers, but it's unclear when that music will reach the public.

THE FILM: A 12-minute clip for the film was previewed for the media last week, showing Jackson practicing and singing in fine form, according to The Associated Press. Though the King of Pop looked frail, he playfully danced with a woman as he sang "The Way You Make Me Feel" and was shown warming up during a performance of "Human Nature."

REALITY SETS IN: Before Jackson's death, ex-Jackson 5 singers Jackie, Jermaine, Tito and Marlon were filming the A&E reality show "The Jacksons: A Family Dynasty." It's still supposed to air in December — and is likely to be a bigger ratings bonanza than it was before June 25. The preshow drama: Will Jackson's three children — Prince (12), Paris (11) and Blanket (7) — appear? A&E reps first said "no" but later pleaded too-soon-to-tell.

MARK YOUR CALENDAR: Speaking of Jermaine Jackson, the singer is still planning a tribute show, "In Memory of Michael Jackson," in London next June. "Several leading artists" will participate, Jermaine writes on thetribute2010.com, and the still-to-be-announced venue will hold 70,000 people. If this thing actually comes together, here's hoping Pia Zadora will show up to revisit "When the Rain Begins to Fall," her smash 1985 duet with Jermaine.
