The Black Crowes And 'The Expendables' Rule The 'Late Night Lineup'

We're still several months away from the premiere of Conan O'Brien's new talk show, which will hopefully infuse the late night field with the same sort of energy it had at the beginning of 2010. As it stands, everything feels a little bit flat at the moment (though it is good to have "The Daily Show" and "The Colbert Report" back in the regular rotation), though perhaps it's just the dog days of summer catching up with everybody. Regardless, that hasn't stopped people from booking top-level talent for wackiness, which is exactly what's happening this week on "The Late Show with David Letterman." He'll talk to such luminaries as Will Ferrell (Monday, August 2), Michael Cera (Tuesday, August 3), Julia Roberts (Wednesday, August 4) and Mark Wahlberg (Thursday, August 5). It'll also be a busy musical week for Letterman, as he'll introduce performances by Damian Marley and Nas (Monday), the Dead Weather (Wednesday) and V.V. Brown (Thursday).

Over on "The Tonight Show," Jay Leno will chat with "The Expendables" director and star Sylvester Stallone (Monday), fellow "Expendables" star Mickey Rourke (Thursday) and, once again, comic legend Betty White (Tuesday, when he'll also talk to "True Blood" star Sam Trammell). It's an extra-loud week of music on "The Tonight Show," as they'll blow out the speakers with Queens of the Stone Age (Monday), the Black Crowes (Tuesday), K'Naan (Wednesday) and Plain White T's (Thursday). The Black Crowes will also play "Jimmy Kimmel Live" on Wednesday, rounding out that show's music lineup that also includes Flo Rida (Tuesday) and Saving Abel (Thursday).

Though "The Late Late Show with Craig Ferguson" doesn't feature any music this week (as is typical of that show), it will feature some fascinating conversations between the host and Eddie Izzard (Monday), Paris Hilton (Thursday) and former model-turned-"Real World" star-turned-actress Jacinda Barrett (Friday, August 5). Ferguson will be competing with Jimmy Fallon, who will talk to Kathy Griffin (Monday), Will Ferrell (Wednesday) and Denis Leary (Thursday) while also introducing music by Trey Songz (Monday), Spoon (Tuesday) and Mike Posner (Wednesday).

As for daytime, we're still a handful of weeks away before Ellen DeGeneres comes back to talk about leaving "American Idol."
