NBC will serve up a sizzling menu of new and returning summer series -- accented by all-new original scripted programming with the series premieres of "The Philanthropist," "Merlin" and "The Listener" – and paced by the new alternative series "I'm a Celebrity…Get Me Out of Here!" and "Great American Road Trip" plus the return of summer's top-rated "America's Got Talent."

In a bold scheduling move, "I'm a Celebrity…Get Me Out of Here!," based on the international hit from Granada America, will debut as a two-hour television event on Monday, June 1 (8-10 p.m. ET) and will be stripped over four weeks in June.

"Medium" will broadcast its season finale Monday, June 1 (10-11 p.m. ET), "Law & Order: Special Victims Unit" will have its season finale on Tuesday, June 2 (10-11 p.m. ET) and "Law & Order" will unveil its season finale on Wednesday, June 3 (10-11 p.m. ET). The new drama "The Listener" will also debut that week on Thursday, June 4 (10-11 p.m. ET).

"The Philanthropist" chronicles the heroic adventures of a billionaire playboy turned vigilante philanthropist. James Purefoy ("Rome") stars as Teddy Rist, a successful tycoon whose life is forever changed after rescuing a young boy during a hurricane in the Nigerian town he was visiting. Rist is spontaneous and impulsive and quickly decides to channel his passion, power and money into helping those in need.
