Before you know it, the summer will be upon us. For viewers, this is both bad and good news. The bad: The major networks resort to schedules filled with reality programming. The good: The cable networks rev up their schedules with original scripted programming. By the time July rolls around, AMC, FX, TNT and USA will be chock full of fan favorites.

For TNT, that means a new season of 'The Closer.' The network has just announced that season 6 will premiere on Mon., Jul. 12 at 9PM. Joining 'The Closer' on that evening will be the new drama 'Rizzoli & Isles.' Based on a series of Tess Gerritsen's novels, the show casts Angie Harmon and Sasha Alexander as a Boston detective and medical examiner, respectively, who team up to solve cases. The series also stars Lorraine Bracco as Harmon's mother.

TNT has always excelled with shows featuring strong female leads. As long as the acting and writing is up to par on 'Rizzoli & Isles' it should have a long life on the network.

Donnie Wahlberg's acting arc has been a positive one, moving from killers and thugs to detectives and heroes. His latest arc will take place on TNT's upcoming police series, 'Rizzoli & Isles.'

The series stars 'Law & Order's' Angie Harmon and Sasha Alexander of 'NCIS' in a drama that revolves around the friendship between Boston homicide detective Jane Rizzoli (Harmon) and her medical examiner friend Maura Isles (Alexander).

If you can't choose one, why not choose them all?

That's exactly what TNT did yesterday with the pickup of three new pilots: 'Delta Blues,' 'Rizzoli and Isles' and the still-untitled alien-invasion series from producer Steven Spielberg. Each show received 10-episode orders, according to the Hollywood Reporter.

'Delta Blues,' from producer George Clooney, stars Jason Lee as a Memphis cop who moonlights as a musician and still lives at home with his mother. The Boston-set 'Rizzoli,' based on a series of mystery novels by Tess Gerritsen, stars Angie Harmon and Sasha Alexander as detectives, with Lorraine Bracco playing Harmon's tough, but loyal mother.

Be on the lookout for a number of famous guest stars to appear on your favorite shows this season. Check out a round-up of some recently-announced apppearances:
