Our star-search summer continues. Fox has ordered eight more episodes of “30 Seconds to Fame” (7 p.m., Fox). The network has given the hook to the sitcom spoof “Meet the Marks” and will air the additional “30 Seconds” episodes in its place at 7:30 p.m on Wednesdays.

For the uninitiated, “30 Seconds” features two rounds of competition between performers who range from dreadful to spectacular. Each act is allowed up to 30 seconds in which to display its talent to the audience. After the first round, the audience decides which three acts get the chance to make the most of another 30 seconds in round two. Following the second round, audience members cast their votes for the lucky winner of that week’s $25,000 grand prize.

NBC is also playing with its schedule to attract fickle summertime viewers. The Monday-night drama “Crossing Jordan” gets a temporary Wednesday berth, airing in the “Ed” slot for the next two weeks.

The Peacock network offers viewers three straight nights to familiarize themselves with “Law & Order: Criminal Intent” (9 p.m.). The Dick Wolf-produced series will run tonight, Thursday and Friday and air back-to-back episodes on Sunday. On tonight’s repeat episode, a plastic surgeon is suspected of killing his drug-addicted wife. Donna Hanover, better know as the former Mrs. Rudolph Giuliani, guest stars as a defense attorney.

The Independent Film Channel celebrates the heyday of blaxploitation movies with the thoughtful documentary “Baadasssss Cinema” (9 p.m.). Directed by Isaac Julien, the film sees movies like “Shaft,” “Superfly,” “Black Caesar,” “Foxy Brown” and “Sweet Sweetback’s Baadasssss Song” as an ignored and under-appreciated genre, and argues that these violent and often outrageous movies were an important outgrowth of the civil rights and Black Power movements. For the first time in mainstream cinema history, audiences from all races were watching movies with black casts featuring black heroes. Some of these films were also directed by black directors.

In addition to great clips from dozens of blaxploitation films, it includes interviews with stars Pam Grier (“Coffy,” “Foxy Brown” and “Sheba Baby”), Fred Williamson (“Three the Hard Way”), directors Melvin Van Peebles, Larry Cohen and Quentin Tarantino and many critics and scholars. We’re also shown vintage clips of civil rights leaders, including Jesse Jackson, who condemned these movies for their violence and negative stereotypes. At the conclusion of “Badasssss,” IFC will air the 1974 Pam Grier vehicle “Foxy Brown” (10 p.m.). “Superfly” (Thursday 9 p.m.) and “Shaft’s Big Score” (Friday 9 p.m.) are also scheduled.
