As part of its busy (see: lots more originals) summer lineup, NBC has picked up new episodes of I’m a Celebrity…Get Me Out of Here! for a special run in June. Having first debuted on ABC in 2003, the reality show that drops D-level celebs into the heart of the jungle will air Mondays through Thursdays for three weeks beginning June 1 and then air Monday through Wednesday during the fourth week of June. “This is a concept that has worked really well, all around the world,” says NBC head of scheduling Mitch Metcalf of I’m a Celebrity…, which is based on an international reality-show format from Granada America. “It will jump start our summer.”

NBC will also stack the deck for Conan O’Brien’s much-anticipated debut as the new host of The Tonight Show on June 1 by scheduling the season finales of Medium (June 1), Law & Order: SVU (June 2), and Law & Order (June 3) — as well as the premiere of the new drama The Listener on June 4 — during that week. The Listener revolves around a young paramedic (The Timekeeper’s Craig Olejnic) who is telepathic.

Two other new scripted dramas will bow this summer: The Philanthropist (June 24) which stars James Purefoy as a wealthy do-gooder, and Merlin (June 21), a 13-parter about the infamous Camelot sorcerer. Besides the return of America’s Got Talent on June 23, NBC will trot out two made-for-TV miniseries this summer, as well: Meteor (June 7), a disaster flick that stars Christopher Lloyd and Marla Sokoloff, and Storm (July 19), a Treat Williams starrer about a man-made disaster gone bad.
