EXCLUSIVE: In his first regular series gig, Tropic Thunder co-star Brandon T. Jackson has been tapped as the male lead opposite Minnie Driver in  CBS’ buddy P.I. pilot Hail Mary. Penned by  Jeff Wadlow, the project centers on Mary Beth Baker (Driver), a suburban single mom in Atlanta who, after her teen son gets killed, teams up with her son’s best friend KZ (Jackson), a fast-talking con artist from the streets, to solve her son’s murder and other crimes. Jackson, repped by CAA and ML Management, most recently appeared in Big Mommas: Like Father, Like Son and guest starred on Fox’s Raising Hope.
