Jonah Hill and Channing Tatum are confirmed to topline Columbia Pictures’ contempo treatment of “21 Jump Street.”

Both thesps, who had been previously rumored to join the project, will serve as exec producers.

“21 Jump Street,” based on the popular Fox Broadcasting series about youthful-looking undercover cops working in high schools and colleges, is directed by Phil Lord and Christopher Miller from a script by Michael Bacall.

Hill and Bacall penned an early treatment of the script with Hill pegged to star.

“Jonah helped create a smart and funny vehicle that is tailor-made for him and Channing,” said Col prexy Doug Belgrad. “They are a perfect duo for this film, and Phil and Chris have a terrific, accessible take on the material.”

Neal H. Moritz serves as producer with the late Stephen J. Cannell, who co-created and exec produced the series and will receive posthumous credit.

Col prexy of production Hannah Minghella and Jonathan Kadin will oversee the project for Sony.

Up next for Hill is Sony’s “Moneyball,” with Brad Pitt, and David Gordon Green’s “The Sitter” for 20th Century Fox.

Tatum has a busy lineup with Universal’s “The Dilemma” set to bow Jan. 14, followed by the sword-and-sandals epic “The Eagle,” with Focus Features distribbing on Feb. 11. He also just wrapped production on Sony’s 2012 pic “The Vow,” opposite Rachel McAdams, and will star in Steven Soderbergh’s “Haywire.”
