*Movie studio Summit has picked up U.S. rights to “I, Alex Cross,” in which Tyler Perry is set to play the detective-psychologist created by novelist James Patterson, a Summit spokesman confirmed to the Hollywood Reporter.

As previously reported, “I, Alex Cross” will be the first major role Perry has undertaken that doesn’t involve one of his own projects.

Idris Elba was attached to portray the detective in an indie due to be directed by David Twohy, but that adaptation appears to be shelved for now, according to the trade.

Rob Cohen is directing “I, Alex Cross” for QED, with QED partners Bill Block and Paul Hanson producing along with exec producers Leopoldo Gout and Steve Bowen.

Summit’s acquisition reteams its chairman/CEO Rob Friedman, with the franchise. During his tenure as Paramount vice chairman, Paramount released the two earlier adaptations of Patterson’s Cross novels — 1997’s “Kiss the Girls” and 2001’s “Along Came a Spider,” both starring Morgan Freeman.
